Where is Minnesota better other than WR and S? I think this is a case where neither team has a lot of proven players, so each fanbase is going to prefer their own team. We all believe the young players on our own team are going to be great, and we have no idea who the guys on the other teams are outside of past contributors and a few highly touted recruits.
I could see an argument for RB, but I'd call that a push at best. Ibrahim obviously had more yards than Washington, but he just had more opportunities. The YPC is similar and receiving definitely in Washington's favor.
Minny probab'y has the best individual d-lineman in Coughlin, but outside of Safety I'd still take Nebraska's position groups across the board. You'd probably do the opposite, but then it's not really "no question." I'd actually even take our safeties (I do love Winfield, but he's really the only guy), but I can recognize that's blind optimism more than anything objective.
Offense
QB: edge Nebraska - no question your guy is a weapon, while our guy (Morgan) is functional. Neither team has great depth.
OL: edge Minnesota - we were okay for half of 2018, then tremendous when Faalele started playing. Between the two teams I think the three best OL (Connor Olson, Blaise Andries, Daniel Faalale) are all Gophers.
RB: edge Minnesota - Ibrahim exceeded 1000 yards as a freshman, then there's Rodney Smith and Shannon Brooks - those three are all killers.
TE: even
WR: edge Minnesota - I like Spielman a lot, but he's only one guy. You're going to miss Stanley Morgan a lot. Tyler Johnson is better than Spielman, Rashod Bateman is better than Johnson was at the same point in his career, and Demetrius Douglas and Chris Autman-Bell both have great potential.
Defense
DL: edge Nebraska - but only slightly. You have better talent overall, while we have the best individual player in Coughlin.
LB: edge Minnesota - our boys are going to excel this year. Thomas Barber and Kamal Martin are experienced and both will probably see the field in the NFL, and Thomas Rush looks like the next big thing. Your LB corps is pretty good, could be very good, but not equal to ours in 2019.
CB: edge Minnesota - this wasn't a strength for either team last year, but we cleaned up our schemes and got much better in the last few games. Your CB performance needs to improve; ours already did.
S: What you said is fair. Winfield is probably the best Safety in the B1G, but nobody knows it yet. The balance of this group favors Nebraska, but Winfield is a huge wildcard. edge Minnesota.
Special Teams
Correct me if I'm wrong, but your kicking game is nothing special and neither is ours. But we excelled last year in the return game.
