Perhaps the BEST B1G Forum anywhere, here at College Football Fan Site, CFB51!!!

MSU has seemingly an entirely new team, but I'll try...

1. K/P - K Matt Coghlin back for a 6th year, and they have a preseason All-Big Ten punter

2. RB - Probably the only position group that I feel is actually a positive.  Collins in hopefully back from his COVID plagued 2020, and Simmons looked pretty good early, before getting hurt.  And those guys look like they will be #3 and #4 on the depth chart behind a pair of transfers.

3. WR - No confidence we have a true #1, but there is so much depth, particularly considering how true freshman Keon Coleman has looked, that I have a hard time believing a really good core of 3-4 won't emerge

4. DB - the starting group I think is possibly a top 4ish group in the conference, but there is frighteningly little depth if the transfers aren't immediate contributors

5. DL - Jalen Hunt may have been their best lineman last year, but couldn't stay healthy.  Panisiuk returning certainly helps.

6. QB - now things get dicey.  It's either Temple transfer Anthony Russo, or RS soph Payton Thorne, who got one start last year when Lombardi was hurt.  Both should be an upgrade from Rocky, or the injured 2019 version of Brian Lewerke, but I don't see it be a position of strength at all

7. OL - the reports have been more positive than this, but I'll believe it when I see it.  This has been a MASSIVE problem for the program since Conklin went to the NFL.  If this can even be a not bottom 4 in the conference unit, the offense should take a massive step forward

8. LB - Adding Tennessee transfer Quavarius Crouch is the only reason this group isn't at the bottom.

9. TE - the core group includes a converted punter, a converted DE, a converted RB, and a true freshman.  It is ugly, ugly, ugly.  I do think freshman Kameron Allen will be good, eventually, but, ugh.  Matt Dotson suffering career ending injuries, and Trenton Gillison never figuring it out left a gaping hole.  No surprise MSU has two TE commits for 2022

For UW, I got...

OL. Experienced, very talented and very deep

LB. Same.

TE. Same.

DB. I'm super-excited to see how this group does. Lots of experience, and also a lot of young talent coming up.

RB. Should probably be higher, but I don't see the home run threat. At least not yet. The Clemson transfer helps this unit.

WR. I very nice group of complimentary receivers. Depth is strong. Someone needs to break out.

DL. Very deep, but not a lot of experience after the top 3 in the group.

QB. Lots of talent, good depth. Lake of experience puts this group here.

ST. Questions abound, except for punter, who is very good.

For UW, I got...

OL. Experienced, very talented and very deep

You can just copy/paste this every year and I mean that absolutely as a compliment.  Wisconsin's ability to acquire and develop OL talent over the last (almost) three decades is astounding.  

1 - RBs.....incumbent is back, plus two 5* transfers, including Bowman from Clemson.  I'm not sure why our RB room is loaded, but it really is.
.
2 - DL.....again, talented incombents return plus 300 lb transfers from Auburn and Penn St.  SOPH Gervin should become a dude this year.
.
3 - QB......Emory Jones will be great and his backup LOOKS like Cam Newton. 
4 - idk, LBs?  We only play 2 LBs usaully, and 1 of them is pretty good.
5 - WRs.....we've lost so much WR/TE talent the past 2 years.  It catches up to us this year.  The talent is young.
6 - DBs I guess?  Like LSU, the parts were a helluva lot better than the whole last year.  It can only get better.....right?
7 - K/P I guess.
8
9
10 - OL.......let's see, we're going to a more run-heavy version of Mullen's offense and our OL can't run-block for shit.  Great.  Can't wait.

I'm just going to give Michigan D's everywhere. Not expecting anything except for Harbaugh to get the can after he loses every big game on the schedule again and gets his face kicked off and boat raced by Ohio State. 

Iowa

1. DB - One of the top DB units in the conference, lots of experience returning. Depth is fairly unproven behind the starters.

2. RB - Goodson is among the top backs in the conference. Ivory Kelly-Martin is a senior who can't stay healthy, but has some experience. A name to watch, Gavin Williams. FB Monte Pottebaum continues the skull cracking tradition.

3. LB - Started 2020 as a huge question mark and ended the season as a strength. Depth behind the starters is shaky.

4. K/P - Return 1st Team All-B1G punter. Replacing Keith Duncan, but Caleb Shudak has looked good this fall.

5. OL - I think interior OL will be one of the best in the conference, but OT is a bit of a question mark right now.

6. TE - Starter Sam LaPorta will be good, very unproven behind him.

7. WR - Lost a couple good ones and replaced them with true freshman. The pair of freshman have looked good so far, but... they're freshman.

8. DL - DE should be fine, DT a pretty big question mark.

9. QB - The season will go as QB goes. If Petras has improved pocket presence and accuracy, Iowa is going to be pretty good. If not, gonna be a long season.

Agree with this for the most part. Only switch I may make is LB to 2 and RB to 3. I think WR is accurate for a preseason ranking but think they could prove to be a real strength by years end. DL is also a question mark to me. Hopeful for them to be effective but really just an unproven group yet. Petras is absolutely the key to the entire season.
