Hello TigerHawkLogo. Looks like you came in peace, but if you didn't pick up on it, some of your fellow fans have only come here and successfully been banned.
Defense - I would expect you to know about Diaco and our switch to a 3-4. Of course we should expect some growing pains, and hope that any bugs are worked out before OhSU. I don't know what kind of quality depth we have on the DLine. Our ILB's should be pretty good. The OLB's are still a question mark. We lost arguably our top rated player, DB Chris Jones, to injury. But we have some experienced DB's returning and some young talent, so I still see us in good shape in the backfield.
Offense - Our OC wants an inside running game and an equal dose of high probability passes. Tanner Lee, a transfer from Tulane, has already been named the QB. There's a lot of hype surrounding TLee but lackluster stats from his Tulane days. We will be seeing new TE's this year. The last I heard was walk-on TE's for our two-deep, but that could be old/wrong news. Quite a few young guys will have a chance to show their stuff at WR. Stanley Morgan and Pierson-El are returning producers at WR. RB is a question mark for us at this point. We want an all-purpose back that is also capable of running inside. My guess will be more running back by committee this year. If pressed to pick one, I would pick Tre Bryant as the RB that emerges as the go to guy. Our OL should be better than last year. Our OL coach claims players can get better on the scout team, so there's no reason to list starts or appearances. Which ever 5 OLineman the OL coach picks will be the guys until they are so injured that we either play with 10, or are forced to play a replacement OLineman.
Special teams - probably the area with the highest level of consistency in the Mike Riley era. Unfortunately, consistently bad. We jettisoned our special teams coordinator (yes, coordinator), so I'm expecting some improvement this year. Pierson-El was a freshman all american his first year as a returner, but he has racked up a couple injuries since then. We all hope he returns to form this year.
NU vs Iowa - too many question marks for me still, and since it's the last game of the regular season, I don't have a prediction for ya.
