Part five in a series analyzing the New York Giants.

That the Giants picked up the fifth-year option on Evan Engram in no way means they are fully committed to him. It was a no-brainer financial move to secure him contractually through the 2021 season.

This is a huge year ahead for Engram, who delights and frustrates the team and its fans, and needs to stabilize his career by staying on the field.

It is too harsh to suggest it is always something with Engram, but is often something with him. He played in 15 games as a rookie, just 11 in 2018 and a career-low eight games last season, missing time with a knee issue then going down with a mid-foot sprain in Week 9 against the Cowboys on “Monday Night Football.’’

That was it for Engram. He underwent surgery Dec. 20 to repair a partial Lisfranc tear, a procedure that needs plenty of time to heal and is never welcome for a pass-catching tight end who relies on speed and quickness to make a living.

Availability is crucial to stamp a player as reliable, and Engram has been unavailable for 29 percent (14 out of 48) of his NFL games. He is a finely tuned athlete susceptible to strains and pulls and nagging issues that limit his time on the practice field and in games. It is a problem and with a new coaching regime in place, this is in some ways a new start for Engram.

You can bet coach Joe Judge and especially offensive coordinator Jason Garrett are eager to check up on Engram’s rehab progress and get him immersed in the passing game. Engram gets a chance to make a first impression with this group, and staying healthy is his first order of business.

He was the final first-round pick of former general manager Jerry Reese, meaning he is not on Dave Gettleman’s ledger if things go south.

This is a heap of negativity for a player with legitimate disruptive skills and a person who enhances any locker room he enters. Engram showed himself to be a straight-shooter as a rookie and is earnest in everything he does while in the building. He had a problem with drops earlier in his career, but the main concern with him is maintaining his body. He has the distinction of hauling in Daniel Jones’ first NFL touchdown pass, and the way Engram turned on the jets on the 75-yard scoring play at Tampa Bay showed exactly what he is capable of doing.

“I want to be part of the turnaround here,” Engram said. “I want to be part of the turnaround that’s coming.”

He will be, if he can stay on the field.

To balance out the position, the Giants signed veteran Levine Toilolo, essentially to replace retired Rhett Ellison as a blocker and jack-of-all-trades. The towering 6-foot-8 Toilolo has 97 career receptions in seven years for three different teams and should be a “throw it up there’’ target for Jones in the red zone, as well as a capable in-line blocker.

“I think for me being a little biased, I always think the more tight ends on the field, the better,’’ Toilolo said. “The tight end position is a unique one in terms of you can have so many different body types and different athletes out there. You can ask them to do a wide range of things.’’

It will be interesting to see what comes next for Kaden Smith. He was a sixth-round pick of the 49ers but got waived and picked up by the Giants. He ended up catching 31 passes for 268 yards and three touchdowns, including the game-winner in overtime in Week 16 against the Redskins — so blame him for the Giants missing out on Chase Young in the 2020 draft. Smith showed a knack for getting open, and that could prove useful.

Garrett Dickerson, from Bergen Catholic High School, has been on the scene for two years, mostly on the practice squad, and will try to stick around once again. The most intriguing newcomer might be Rysen John from Simon Fraser University in British Columbia. John is 6-7 and he caught 10 touchdown passes in 10 games last season. At the very least, he will be noticeable on the field in training camp.
