Casillas to SS and Rex Ryan's Scheme

Also people saying he cant cover u have to understand, rob ryan runs a 3/4 hybrid kind of like a 4-6, his SS is basically always in the box, He wouldnt be covering WR's he would either be blitzing or covering the tight end, or u could take ur ILB to over the Tight end and put ur SS on the RB or FB actually, but like i said the SS in rex ryan's system is basically a SS, on rushing downs u can have casillas play SS, in passing downs take him out and move IAQ to SS
