in all honesty i am a flacco supporter, and he has been playing terrible,
He is constantly throwing off his back foot making his passes terrible, watch some game film and check out the wobble of the ball on his throws, He is still however a good QB when he steps into his throws, far more accurate and a way higher completion percentage,
Last years ACL injury has really messed him up mentally, He is afraid to take the hit that he has taken his entire career, whitch i dont really understand since he was hurt being rolled up on by his own Offensive Lineman and not an actual opposition player.
His gun shyness this year is far more noticeable this season, weather it is because he doesnt have the chemisty with his recivers; or that mentally he doesnt think he can make the throw is anyone's guess, Joe has steadily become more and more gun shy going back to the 2013 season, I personally have found my self yelling at the TV or at the game to 'Fire It' more and more often.
Personally i believe some of his trouble is that he wasnt mentally ready to come back on the field after a season ending injury, i also believe some of his problems are associated with the terrible line play that has given him less time in the pocket and few opportunities to step into his throws: this seems to be the case as he has progressively gotten worse as injuries to the O line have mounted.
