We have DT's (Stroud and Williams)
We have 1 DE (Schobel) if he comes back which i assume he will
In his point moving Maybin to OLB
So that leaves 1 DE, 1 LB to obtain via draft or Free agency
Right now we are built for a 4-3 Defense.
We also need offense LT,QB, A RB with speed, and a WR. So by my counts we need offense more then defense and the transition would be to difficult and cap consuming, and we would be stuck with the same offense as last year where are Defense held teams but our O could not score for the life of them.
