but look at it based on what Saban said he's going to do: Draft the guy with the biggest "long-term" value to the franchise.
The average career of a RB is about 4-6 years, whereas a QB can play till his mid 30s (sometimes even longer) and still potentially be at a high level.
Ronnie Brown for example is turning 24 this December. Alex will be 21 in May, and Aaron will be 22 in December.
So, in 6 years, Brown will be 30, whereas Alex and Aaron will only be 27 and 28 respectively.
Its no secret that RBs usually start to decline at 30, because of all the hitting they take, whereas QBs last much longer. Curtis Martin is like the lone exception, and he would've probably not done nearly as well if he didn't have LaMont spot him from time to time.
I understand that you want a RB, but wouldn't you potentially like to have stability at the position for a potentially 15 years? I think that is "long-term" value
