Agree with Rich on WRs, we have studs in the stable there. Expect that Gaul steps in for Kurfis with no problem.
Not so sure on RB, have hope for Brown but you need more than one RB to make it through a season. Unless a stud Frosh shows up I see this as a big ????
As to the D, get a real coordinator and change the scheme. Only the returning LBs impress me.
