It has been said before, and it will be said again (at least a million more times): It is too early to panic over players, especially star players, getting off to rough starts.

With that being said, if you see someone thrown into a frenzy because one of their key draft picks isn’t playing up to their expected standards, and that person is looking to strike a deal, make sure you are ready to buy.

A duo of Cubs starters (Yu Darvish and Jose Quintana) may be available from owners who believe three or four starts tell the complete story.

Because Darvish is 0-1 with a 6.00 ERA and has his highest walk rate (4.2 per nine innings) since his rookie year (and that’s largely because of the four walks he issued in his Cubs debut), they think he is on the decline. Because Quintana (1-1, 8.16) has 10 walks to nine strikeouts, and has had a slight decrease in velocity, they think the lefty is toast.

It is too early to throw in the towel on these guys, but if someone in your league makes them available, be sure to be first in line.

Darvish is striking out 10.2 per nine innings while averaging 94.87 mph on his four-seamer, right in line with his career average. The main problem: He has been unlucky. He has a .325 BaBIP, has a 21.4 HR/FB rate (way above his 12.2 percent career average) and he hasn’t been getting as many swinging strikes (9.6 percent, while he averages 12.1 percent). Once the weather warms up and Darvish gets used to his new team, he should be the pitcher you expected when you drafted him.

As for Quintana, March and April always are unkind to him — he is 9-9 with a 4.39 ERA (worse than any other month) and a 1.363 WHIP (also worse than any other month) through the end of April in his career. He has been a consistent fantasy option since 2013, posting a respectable 3.50 ERA and averaging 10 wins in each season since.

As always, Roto Rage preaches patience. Just as you wouldn’t expect a baby to walk two weeks after it’s out of the womb, don’t expect players to be in midseason form when they’re pitching in crazy weather or in new environments. But, if someone wants to panic and believes they know the full story, take advantage of their shortsightedness.

Here are some other buy and sell options to consider:

Sell: Everything in Boston right now is turning to gold, so it is understandable for Eduardo Rodriguez (2-0, 3.45 ERA, 1.277 WHIP, 11.5 strikeouts per nine) to garner some attention. It also is understandable (and realistic) to believe the Red Sox will not keep this pace forever, and the injury-prone Rodriguez will find himself on the disabled list after sneezing.

Stand pat: Some may believe this is the perfect time to sell San Diego’s 24-year-old rookie Joey Lucchesi, who is 2-0 with a 1.66 ERA and 25 strikeouts (10.4 per nine innings) over his first four starts. Roto Rage, however, believes this is the time to do nothing and reap the rewards. He may not have been a top-tier prospect, but he had success through 39 games in the minors (11-9, 1.99 ERA, 10.1 strikeouts per nine), and there is nothing better than a young arm who turns into a fantasy asset.

Buy: It has been a rough start for Jon Gray (1-3, 6.23 ERA, 1.523 WHIP), but he still is striking out a career-high 9.6 per nine innings and walking a career low 2.1 per nine. His 3.64 FIP, .385 BaBIP, career-low 39.4 percent groundball rate (44.9 percent for his career) indicate he has been unlucky, so there is reason to believe he should turn things around. But, it is a good time to take advantage of someone panicking early.

Sell: Vincent Velasquez is off to a solid start (1-2, 3.80 ERA) for the Phillies, but he is far too reliant on his mid-90s fastball — throwing it nearly 60 percent of the time. The 10.1 strikeouts per nine are nice to have, but his arsenal, mixed with a history of injuries, should make you want to take what you can get for him.

Buy: Robbie Ray is walking 5.8 per nine innings and allowed 13 runs (12 earned) en route to a 4.98 ERA over his first four starts. This, however, is life with Robbie Ray. The Diamondbacks lefty gives up runs, he walks a lot of people, but he also strikes out a ton (13.3 per nine innings). If you see an owner dangling him in your league, take advantage. If you own him, however, keep him in your rotation.

Yasmani Grandal C, Dodgers
Entered Friday night with an eight-game hitting streak, going 12-for-34 (.353) with two homers, 10 RBIs, five runs scored, four walks and a 1.083 OPS in that span.

Gerrit Cole SP, Astros

Has allowed just three earned runs (all on solo homers) over his first four starts (0.96 ERA) while striking out 41 over 28 innings (13.2 per nine innings) and walking just six (1.9 per nine innings).

Javier Baez 2B/SS, Cubs
Was red-hot entering Friday night, going 10-for-29 (.345) with five homers, 12 RBIs, nine runs scored, one stolen base and a 1.367 OPS over his past seven games.

Jeimer Candelario 3B, Tigers
Entered Friday having hit a homer in three of his past four games, going 9-for-17 (.529) with six RBIs and a 1.732 OPS in that span.

Miguel Gonzalez SP, White Sox
Has allowed 17 earned runs (12.41 ERA), has walked (six) more than he has struck out (five) and has allowed four homers. Opponents are hitting .400 against him.

Kenley Jansen RP, Dodgers
Not only has he already blown more saves this season (two) than he did in 42 opportunities last year, he has allowed six earned runs, is striking out a career-low 9.5 per nine innings and is walking 4.1 per nine.

Alex Cobb SP, Orioles
He did not get out of the fourth inning in either of his first two starts, allowing 15 runs (12 earned) over just seven innings en route to a 15.43 ERA. Opponents are hitting .500 with a 1.399 OPS against him.

Tim Beckham SS, Orioles
Had just three hits (all in Thursday’s game) in his past 23 plate appearances (.150) with three walks, eight strikeouts, no stolen bases and a .461 OPS.

— Lewis Brinson has three hits (two of which were homers on Thursday) in his past 42 plate appearances for the Marlins. The 23-year-old is hitting .077 with two walks, 16 strikeouts, a .122 OBP and .353 OPS over his previous 12 games before Friday.

— No one expected Logan Morrison to repeat what he did during his breakout 2017 campaign, but no one expected him to be this inept either. Through his first 12 games, the Twins first baseman has three hits in 44 at-bats (.068) with no homers, two RBIs, 12 strikeouts and a .271 OPS. Entering Friday, he was also hitless in his past 13 at-bats (including an awe-inspiring 0-for-7 effort on Wednesday). FYI: Through 12 games last year, he was hitting .325 with three homers, 10 RBIs and a .916 OPS.

— For the second straight year, a veteran Rockies closer is leading the league in saves. Greg Holland was a dominant force out of the bullpen last year en route to an NL-high 47 saves, and Wade Davis has already racked up eight this year. There must be something in the water … which probably comes from one of the 500-plus dispensaries in the state. Right on, man!
