Damyean Dotson’s alma mater is in the NCAA Tournament’s Sweet 16 — a sweet capper to his resurgent second season.

Nobody is more proud to be from Houston than Dotson, who has remained close to the University of Houston program and runs a children’s charity in his hometown.

It was a natural he and rookie teammate Kevin Knox would engage in a major bet as Houston faces Kentucky.

Though there was talk of a monetary wager, the final agreement is the player whose university loses Friday’s game has to show up in the winning team’s jersey for Saturday’s Knicks game at the Garden. If Dotson arrives wearing Kentucky blue and white, he’s not going to be in the best spirits.

“I hope we get the win,’’ Dotson said. “Houston is a good defensive team. I haven’t seen Kentucky much. I watched our team a lot this year. I’m going for them, of course, to get to the Elite 8. I don’t want to speak too soon and jinx them. Last year, I did a bracket and we lost in the [round of] 32. No brackets, not calling coach, not texting anyone on the team.”

After a rather invisible rookie season as a second-round draft pick by Phil Jackson, Dotson has been one of the pleasant surprises this year and has started at shooting guard since late January, when the Knicks dealt Tim Hardaway Jr. in the Kristaps Porzingis trade. Even before then, Dotson was hitting 3-pointers and defending fiercely.

In fact, coach David Fizdale recently called Dotson his most consistent player this season, and said his relentless hard work after a lousy summer-league performance in Las Vegas has led him to him becoming a piece of his team’s future.

Dotson said he only spent two weeks last summer at the University of Houston training. Otherwise, he was in Tarrytown working with the new coaching staff. He’s close with newcomer DeAndre Jordan, also from Houston. In fact, Dotson and Jordan’s younger brother are best friends.

“The opportunity is great,’’ Dotson said. “Like last year, I always said if I get an opportunity I’ll take advantage of the opportunity. That’s what I’m trying to do. Coach is giving me a chance.’’

Dotson has played 1,743 minutes this season — compared to 474 last season when he spent 13 games in the G-League. He’s averaging 11 points on 42.5 percent shooting — 37.3 from 3-point range

“I’ve been getting my shots and getting my looks and learning how to come off pin downs, pick-and-rolls and getting to the basket more,’’ Dotson said. “It comes with experience, with more games played. You go in and get your shot blocked, you know you have to go in next time with something different. With opportunity, you get more chances to work at it.”

Dotson’s minimum contract is non-guaranteed for next season, but he’s surely a keeper — even if GM Scott Perry didn’t draft him. Several teams inquired about Dotson at the trade deadline partly because of his good contract situation.

From 2017-18 afterthought to one of Fizdale’s finest developmental works.

“As far as showing what I can do, it’s more than last year,’’ Dotson said. “I’ve been able to show different parts of my game more than last year with the minutes.’

Now his goal is to have Knox wear Houston’s scarlet red and white Saturday before the Knicks host Miami. Dotson played for the same Cougars’ coaching staff and with a few of their starters, including stars Galen Robinson Jr. and Armoni Brooks.

“We talked today in the weight room,’’ Knox said. “He’s talking a lot of trash. I talk my trash, too. It’s going to be a fun matchup.’’
