This is the Depth Chart I would predict right now. The first change I would probably make would be to drop Chris Scott to the Practice Squad if we need a separate Long Snapper. I'm hoping Pouncey or someone else on the roster can prove capable in that spot, but that's probably wishful thinking.
The second move would be to drop Doug Worthington to the PS if Arians decides he wants/likes another back. I would love for Summers to prove that he deserves a spot, and I know lots of BTSCers are in love with Redman.
