So, you think McVay prefers more of a move TE? If Higbee is an indicator, then he wants a guy that blocks well and can catch/run.
I think Warren is similar but more athletic than Kraft. I can't say with Mayer, I've never seen him play. Warren runs routes well And he gets separation like move TEs do.
If Warren had come out in the draft last year, he's the PSU TE I wanted the Rams to draft. I know you think this is all Kotelnicki, but the year before when Kotelnicki wasn't at Penn State, Warren split time with two other drafted TEs (Theo Johnson and Brenton Strange) I thought he was the best of the three despite not being the featured guy and not being as athletic as Johnson. I'm not saying Warren is as good as Bowers. Bowers has unusual speed and still can block.
Andy Kotelnicki said that Tyler Warren is the smartest player he's ever coached. That includes every position. That is the type of player McVay likes in his pass game.
