Biggest concern for The Offense and Defense?

The only concern is Marcel, but I chalk the questions about Marcel being able to throw the ball to our absolute arse wide receivers last year. Our best guy, Noah Thomas, was the 25th best in the country. Finally having weapons at WR will showcase exactly what Marcel can do.

After that, we have the deepest, most experienced O-line in the SEC if not the country. We have 4 weapons at WR in Bussey, Concepcion, Craver, and Bethel-Roman. We have 3 weapons at RB in Owens, Daniels, and Moss. We have 3 weapons at TE with Theo, Amari, and Bodecker (whatever his name is). The offense will be solid, probably top 3 in the SEC this year if not the best offense in the SEC.

The defense has new faces at D-line but I like the guys they brought in. We have experience there and I'm thinking the freshmen are going to do some pretty nice stuff there as well as the transfers. Marco Jones and Cashius Howell are going to get after some QBs.

We have excellent talent and depth at LB with Taurean and Scooby leading the pack, but guys like Lockhart will provide great depth rotation there as well.

The cornerbacks looks to be damn good too. Will Lee and Dezz Ricks are solid, but Tyreek Chapell and Jordan Humphey are going to provide a ton of depth there as well. And the safeties with Ratcliffe, Brooks and Anderson plus some freshmen depth there as well...

I mean, there really isn't any holes on this team and the Aggies may get more production out of their D-line than was thought by the previous guys there.
They can win in a boat race, they can win on the ground, and they can get negative plays with the defense.

Combine that with some excellent special teams weapons and one of the best punters and kickers in the country...this team is going to win a lot of games and surprise the shite out of a lot of analysts by making the playoffs for the first time since they should have in 2020.
