Great move by the Saints. Casillas is too good to be just a backup to Shanle at WLB. He needs to see the field as a starter and get starter's reps. Also, Shanle has played strongside when he was with Dallas and I think in his college days, so it's a position very familiar to him. The WLB needs to be athletic and fast, something Casillas definitely has over Shanle. Shanle has the strength and size to play SLB, better than the smaller Casillas. Very happy with this development. Ingram can spell Shanle at SLB whenever he finally gets healthy. Arnoux will be probably end up as backup WLB. Shanle could fill that role as well.
