I think this has been posted, but rumor has it they want to go two TE sets, with focus back on running game. Boss and Moaeki are solid blockers to help that.
Boss is one of those players that has found out about the grass on the other side of the fence. He will never hold the relevance to a team that he held with the giants.
i was on that myself RC.... but i guess if hes a dece blocker and they doin two TE and two backs... provided denver dont get peyton... could be a nice minor improvement
