WRs are slots. Height not important as much as speed and hands. Gamble has that in abundance.
Not sure what your issue is with LBs. We have a lot of them including a pile of A-S guys in the ladt 2 classes. Other than a stud NG ee have good players available at all spots. The problem to me is the scheme. Neither staff nor players had ever played in it before. Compound that with the injuries at Rover and SS and you have too many inexperienced kuds and coaches trytding to run a D. A dismal failure. Is keeping it all in place the best solution?
