I imagine that the TE's will be coached by Coach Fischer and partly by the OL coaches, unless they find a GA with TE experience which I am not surehow likely that would be?
Sounds like Bo told him he (Beau) "shouldn't be worried about being coached by a good coach" and Bo may already have some guys in mind.
It would probably make sense to bring in a replacement "TE coach" as that would mean the rest of the offensive staff wouldn't have to change what they've been doing. Maybe the same reason we have Ganz as a GA as we don't have a true QB coach.
