Just to be clear to everyone I'm not a Austin hater, I just expect more out of the guy.
I think this board is too quick to blame the coaching and scheme. With the same coaching and scheme Britt was able to reach 1000 yards. The scheme doesn't make Austin run bad routes. The scheme doesn't limit Austin's ability to make a play on the ball. That's 100% on Austin. Until he improves his game it won't matter what the scheme is. Austin has shown he is capable of making big plays here or there, but he hasn't shown an ability to be a consistently productive player.
I expect more out of him too. He needs to become a more consistent route runner and pass catcher. However, Austin's size limits his ability to make a play on the ball.
Britt was able to reach 1000 yards. But Britt is also a 6'3" 225 pound WR who can win jump balls and use his body to box out CBs in close quarters.
It 100% matters what the scheme is for Austin, even if he improves. Austin will never be a WR who will thrive in traffic. Austin will never be a WR who wins jump balls with any sort of consistency. Austin will never be a WR who will outmuscle defenders to get the ball.
That's not who he is. Austin will thrive in an offense that schemes him open. Austin will thrive in an offense that gets him the ball in space. Austin will thrive in an offense that can force the defense into man coverage against him.
Austin needs a scheme that plays to his strengths. When you have a scheme that led to congested passing windows and no real space, you're not going to see success from Austin. Austin is too small for that sort of scheme. You're making things hard on the QB because of Austin's small catch radius. And you're making things hard on Austin because you're negating his strengths.
What I love about Kyle Shanahan is that he's been able to get the most out of pint-sized WRs like Taylor Gabriel and Andrew Hawkins. I think he's a guy who will be able to scheme the sort of space and match-ups that Austin needs to thrive. At that point, it will be on Austin to win those match-ups.
