Yes, I know that Dayan Lake and Riley Burt are coming in next year, but no way Davis goes back to WR. Field corner is the most demanding position athletically on the field by far, and we usually only have 2 guys on the entire roster who can play it.
Guys like Kurt Henderson and Colby Pearson can be successful at WR. At field corner, that just isn't the case.
It would be epic stupidity to move Davis back to WR.
