Sorry, but no team goes 5 wide without one of them being a RB. The RB is needed because they can motion him back into the backfield to block if needed. Also, with Shontrelle and now Nealy, I think that we WANT them to catch balls out of the backfield, not sitting on the sideline on passing downs.
I also believe that TE will always have a place in this offense. Herman had it at Rice with Casey and now at ISU with Franklin. The TE gives you versatility in this offense. A good one can line up wide and go across the middle, block a DB on a bubble screen, attach to the formation and block a rush end or be a lead blocker for the RB. Do we have one like that this season? Probably not, but we have group of guys that can all do certain parts of it.
For WRs, yeah I was exaggerating with 6. But I DO think that 11 last year and 12 this year is overdoing it a little. I'd like to keep that number at 10. I'd bet that you could count on one hand the amount of times that ISU has lined up with 4 WRs on the field in the past two years. That may go up a little this season, but it won't be more than a handful of times.
The thing with the WRs this year is that a bunch of them are graduating this year or next. You have to be constantly refilling the ranks so they can develop enough to play significant minutes. Unfortunately it is rare at ISU when we get a WR to come in a contribute from day one. Then you have to account for attrition, and injuries. Having more than just a two-deep for each of the 3 main WR spots also allows the newcomers to redshirt and gain strength and skills for the future.
The only schools that come even close to having a max of 8 WRs (much less 6) are Army, Georgia Tech, and Navy, because they run the triple option most of the time.
