Heading into the season, much of the buzz and attention surrounding Michigan basketball had to do with all the new pieces.

Coach Dusty May’s portal haul was rated among the best in the nation, with three transfers — guard Elliot Cadeau, forward Yaxel Lendeborg and center Aday Mara — being named to preseason watch lists for the top players at their respective positions.

The fourth and final transfer, forward Morez Johnson Jr., and the top-ranked freshman, former Orchard Lake St. Mary’s star Trey McKenney, each shined in their regular-season debuts with 20-point performances.

Yet, May doesn’t want people to forget about returning players Nimari Burnett, L.J. Cason, Roddy Gayle Jr. and Will Tschetter and their importance to the team. He said as much when he brought up the foursome unprompted when speaking about this season’s roster at the midway point of summer workouts.

“We’ve sat here and Tschetter’s name has come up one time and Nimari Burnett’s name hasn’t come up yet,” May said in July. “The continuity they bring, the character that they bring, the work capacity, the unselfishness where they’re trying to help the younger guys 24/7. They’re spending their time and energy trying to help guys that could potentially chip into their minutes because they want to win and they want to be great teammates.

“Then you throw in Roddy Gayle and L.J., when the prognosticators are talking about we went to the portal and signed this guy and that guy and we brought in this five-star recruit and this four-star, those guys get lost in the shuffle. But if we win this year at the level we’re capable of, if we max out as a group, those returners are going to be a big reason why.”

May’s praise didn’t stop there. During Michigan’s media day on Sept. 30, he called the quartet the “biggest, most pleasant surprise” in the preseason.

“I will say our returners have improved drastically. All four of the guys that were in the rotation last year are much better basketball players,” he said. “Roddy Gayle (in practice) probably had as good of a two-week period as anyone in our program. You guys know how I feel about Nimari. His level of consistency, his routine, his mentorship to the young guys, he just brings so much to the table.

“Then you factor in Will Tschetter, who’s becoming a real shooter, someone who’s able to shoot on the move, get it off quick, not just be a spot-up guy, and he’s able to defend the ball. … Prior to (an ankle injury), L.J. was playing at a significantly higher level than he played at last season.”

May called Burnett a consummate pro and a culture builder with the way he approaches everything. On the floor, he doesn’t care if the ball is in his hands and he doesn’t try to do too much. He simply finds his shots in the flow of the game. Off the floor, May said Burnett attacks his player development plan at an “A-plus level” and acts as another assistant coach with recruits.

As for all the roster additions, Gayle described Burnett as the “perfect leader” for the newcomers.

“If you are confused on what to do, just follow Nimari,” Gayle said at Michigan’s media day. “He always has a steady incline where he’s always getting better just by the basics. I think that’s one thing Nimari does well. He does the basics well, probably the best I’ve ever seen, as far as like stretching, taking care of his body, lifting. You know what you’re getting out of Nimari every day; same with Will.”

Given Burnett’s, Gayle’s and Tschetter’s background of experiences and veteran status, they are the three May turns to any time he doesn’t have “a great pulse” on something with the team or needs help figuring things out that he hasn’t yet.

There’s also an added level of familiarity between the coaching staff — which remained intact — and the returners. Everyone knows what’s expected, even if some roles are different than a year ago, with Cason and Gayle taking on more playmaking responsibilities and Tschetter playing more at small forward.

Gayle, for example, was trying too hard to fit in and “please” his teammates and coaches at times after transferring in from rival Ohio State, May said. Now, Gayle looks much more comfortable.

While Gayle’s midseason struggles last season might lead some to underrate what he can bring to this team, assistant coach Mike Boynton Jr. believes a “life-changing year” could be in store if Gayle commits himself to being one of the best Big Ten wing defenders in a league that has a bunch of talented perimeter players.

“If he can make a mark for himself (on defense), he can do well individually, but obviously that’s going to be a big part of us being successful,” Boynton said. “Then on the offensive side, I think there’s a little bit less pressure. All the noise about him coming from Ohio State has dissipated … and now he can just be him as a Michigan returner and be able to play with more freedom and less focus on trying to prove something about who he is. Just be a good player on a really good team.”

Out of the returning cast, Cason has the most natural room for growth and potential to make a greater impact than he did as a freshman, when he turned in several strong postseason performances.

The highs and lows Cason experienced shaped him and should help him become a more consistent contributor, even though he’s been banged up in the fall.

“I think he took all of it in and committed himself to just maturing, being more organized, taking the off-the-court preparation seriously,” Boynton said.

Just as vital as Cason’s ability to get into the lane, collapse the defense and make plays is Tschetter’s ability to connect the defense with his communication and connect the offense with his spacing.

May said it’s noticeable when Tschetter is and isn’t on the floor at practice due to his effort, energy and enthusiasm. In the exhibition against St. John’s, May felt the Wolverines looked like a different team down the stretch when Tschetter was in the game compared to when he wasn’t.

“I’m excited for all of them,” Boynton said of the core four. “Roddy had a good offseason and preseason. Nimari has been as solid as they come. Will is probably as consistent as they (come). He is who he is whether he plays eight minutes or 28 minutes. … They’re all going to play a big role if we do the things we would like to do.”

That’s not lost on May and the rest of the staff. None of them overlook or underestimate the value of Burnett, Cason, Gayle and Tschetter and how the returning pieces will factor into this season’s roster puzzle as it takes shape.

“If we’re ever going to be at a championship level — and time will tell if we’re going to be at a championship level this season — a big part of it is going to be because of the leadership and continuity of those guys,” May said.
