The schedule is filled, so any conversation about all of these other teams, who Mentor should/shouldn't schedule, who should schedule them, etc. are all irrelevant. Here is some relevant info on the 2020 team:
QB - Ian Kipp
RB - Riley Coughlin
WR - Hutch Baird
WR - ?
WR - ?
WR - ?
LT - Hunter Colao
C - Stan Zalewski
RT - Tommy Shea
LG - ?
RG - ?
Offensively, the team is pretty set at QB, RB, and the offensive line. Wide receiver is a huge question mark. Baird stepped in after Vernon got hurt. His numbers (25 catches, 269 yards in probably 8 or 9 games) were fine as the 3rd or 4th option. Underclassmen listed on the two-deep in 2019 were Eric Coode, Sean Allgood, and Colin DePasquale. In garbage time last year, which you won't see many passes thrown, the trio combined for 5 catches.
DE - Brenan Vernon
DT - Preston Cardina
DT - ? (maybe Benny LoDuca)
DE - Greg Predina
LB - Evan Boyd

DB - Noah Gladish

Last year's two-deep chart had three junior linebackers listed as backups (Jeff Norwood, Andrew Edward, and Aiden Limtury). Along with Boyd, those guys should be in the mix for starting linebacker spots. I can't say I know anything about any of them other than seeing Norwood on the JV basketball team the past two years. I honestly can't say I noticed any of them on the football field, but I'm not super observant about backups. In the secondary, three sophomores were listed on the two-deep (Mike Harrison, Antonio Bertolami, and Kenny Jordan). Gladish is by far the most experienced returner, as he has been starting since he was a sophomore.
Over the years, Mentor has gone back and forth between a 3-4 and 4-3 defense. It is hard to argue last year's results with a 3-4, but I strongly feel the team needs to go back to a 4-3. Last year's defense had a lot of talent and experience at linebacker, so four of them was justified. In 2020, the strength on defense is the size, depth, and talent up front. Use four guys. Let Vernon be in one-on-one matchups all season. I hope that is the case this season. On top of the three experienced guys they are bringing back, I'm sure there are some other guys that can contribute. LoDuca was a big sophomore I noticed playing in the Shaker game. He looked like someone who could step in and start in 2020.
Edit: As for special teams, kicker Andrew Smith is returning. I know he missed a couple FG's in the state semifinal, but he hit 9-11 FG's before that point, including a couple in the 40's. He missed just one PAT all year...can't remember if it was blocked or not. He is a pretty good kicker and it is nice to bring him back.
