Could Stafford be Injured?

[detroit4life]

A buddy of mine pointed out during the game today that maybe stafford is throwing these side arms because he has a shoulder injury and can't throw at a normal angle.

It makes sense, it almost seems like all of his throws are now at some degree of slant. He has taken some big hits all year and definitely has the toughness to play through an injury like that.

Just a random observation, curious what people think.
