Ula needs someone behind him and we need more RB talent period. And as you mention our WRs just won't get it done in this system. None of them are playmakers.
I know you don't want to rely too heavily on JC players, but if the offense isn't going to be tailored to personnel you better go find personnel that are tailored to the offense.
If not, we are going to see more of the same next year.
