You do not know that.
Do you think our Defensive Line is going to be better than the Defensive Line was last year? (Jensen got injured)
Jensen was terrible whether he got injured or not. Not sure why that matters. In any case, you failed to mention the loss of Morrissey which I'm noticing is becoming a bit of a habit from you. Morrissey was the best defensive lineman ISU has had the past several years. His loss is not something I would just forget to mention. I think the dline will be better up the middle and worse at the ends.
Do you think our Linebackers will be better than last year? (Remember that Miller got injured, Peters was injured, Knott was injured, Harris was Redshirted)
Who knows? Sounds like Harris is playing better than he was a year ago which is a positive sign, but it doesn't mean anything to me until he does it in live action. Knott isn't even practicing and he may not play again. There's still a lot of ??? here for you to be making blind statements.
Do you think our secondary will be better than last year?
No I don't. Might be as good, but not better in my opinion. Tribune is decent and Cotton-Moya is good if he can stay healthy. The other two spots are big question marks. Losing Mutcherson will hurt.
Do you think our Offensive Line will be better than last year? (Dagel, Burton, Lalk, Dunning all injured)
No I don't. They lost their center, leader, and best player in Farniok. When we've seen them in action without Farniok in recent years it has been UGLY. I would never assume they are going to be better at this position until they prove otherwise.
Do you think our QB will be better than last year? (SR returns)
Should be better. Especially with a healthy WR core. Bibbs was one of his favorite targets and he's gone so the lack of production at TE will hurt. Biggest question here is will he have time to see the field and deliver?
Do you think our WR's will be better than last year? (Bundrage, Medders injured whole year. West out part year, )
If they can stay healthy absolutely.
Do you think our kickers will be better than last year? (both return)
Should be.
Do you think our RB's will be better than last year ? (lose Wimberly, Nealy) (return Brown, Syria and gain Mike Warren)
Should be, but that isn't saying much. Sounds like there is some young talent here. Again, won't be sold on it until I see it. Young guys can be talented and show promise but they have to take care of the ball and they need a decent line to block for them.
IMO, those are almost all yes and in a couple of cases we are at least as good. What are your answers?
