If Tannehill played like Manziel in any of Manziel's other games this season, FH would already be trying to put him in the Hall of Fame. I think there's more meat on the bone with Tannehill. I think a system more like the one in Seattle would do wonders for him and the team in general.
I think the LSU game was more about LSU thoroughly dominating A&M physically on offense and defense. LSU's DB's were able to hold and interfere with A&M WR's all day, and apart from Mike Evans, A&M's WR's don't match up with LSU's secondary on a physical level. The play where Evans was interfered with and dropped a TD pass summed up the game. No call on the PI, dropped pass in the end zone. If Manziel had 3 TD passes on the day (which he would have with the two drops), people wouldn't be saying that Manziel had such a terrible day. He did miss throws, no doubt, but look at the conditions. Mettenberger (who should go in the 1st RD) was 11 for 20 despite having two outstanding WR's and 8 or 9 defenders in the box all game. The weather was an issue for both QB's. The difference is that Manziel is asked to do everything for his team every single week. It's a recipe for losing, and Sumlin should take a better job elsewhere at season's end, but Manziel is brilliant enough to beat SEC teams despite QB'ing for a Big 12 team.
