I actually like this move. Our TEs mostly only run block (which is Cotton's forte) and he has a lot of experience with the running game and how to rotate RBs effectively.
I think this is a move to put a GA with Garrison for OL. Make the TEs better at run blocking as well as keeping the RBs carries more evened out.
The only fault the defense had was they were on the playing field far too long.
but personally I would have rather seen them move him to a more obscure position (e.g. putting him in charge of the equipment managers or the valet parking.)
