I have watched them try to make Austin into Amendola for the past 3 training camps.  He just doesn't have the skill set to make it work.  When TJ Moe runs these routes BETTER than Austin, it's time to just stop trying to force a square peg into the round hole.  Austin can be a playmaker and a valuable piece of this team.   Just seems to me that there a lot of people who still considers him a WR first and foremost and think he is something more than he actually is. 
Even going back to all of his success at WVU.  It wasn't as a pure WR. It was as a multidimensional "weapon".   He had monster days as a RB, returner, and yes as a receiver.   But he was never the primary threat as a WR.
