Its not the only thing. The lack of comeback and game winning drives, being at his worst in the 4th quarter of games and in late December factor in as well.
I don't think those stats are too bad for Tannehill. Not as good as we'd like but it's not bad. You listed Aaron Rodgers before.. he has only 8 4th quarter comebacks from 2005-2014 (10 years)!! Tannehill has 7 in 3. Joe Flacco has 14 in 7 years, so Tannehill is better than Flacco on this stat, etc.. http://www.pro-football-reference.com/leaders/comebacks_career.htm Point is, Tannehill needs to improve on these things, but it's not justified to say he's a choke artist in the 4th quarter. EDIT: Also, Tannehill had his worst ratings in September (in 2012 and 2014) and October (2013). December was on the better side: http://espn.go.com/nfl/player/splits/_/id/14876/ryan-tannehill
Roy can't be taken seriously. He is a card carrying Tannehill hater, most likely jealous of his wife. He runs the same garbage at Finheaven. I blocked him and I suggest everybody does the same. No time for agenda driven drivel.
