I still think that if Mannion is actually good at being Kirk's "bench buddy" QB coach, make him part of the coaching staff and quit pretending he's a legit option as a player. Actually apply the upside he supposedly has.
As for Mond...I just never see much of anything, beyond a few plays per game, that makes him memorable whatsoever. He looks like so many other young QBs that have the physical tools, but are kinda stunned in the lights of even preseason games.
Mullins already looks better than everyone else behind Kirk, so make him #2 in any case.
