Right now he's no different than TM or AM with the two games he's played. All three have wheels but are one lower extremity injury away from being merely pedestrian. At this point, I don't see the it factor so will avoid any HH prehype until he proves otherwise.
Yesterday HH fumbled a snap, froze when the blitz was in his face, stares down receivers, lucky a couple passes weren't intercepted and poor awarness on outside blitzes. Last but not least, all options are keepers which teams will figure out.
Plain and simple, he's a serviceable QB who's done well against lesser teams. HH wouldn't be a starter, let alone a backup on any P5 team with a heartbeat.
