Disagree. He's absolutely NOT a lock. At some point you have to move on if you don't think the player will improve significantly. There is a new GM and a new coach neither of whom have any loyalty or responsibility towards Hardy. There's also been several reports about Hardy making the same mistakes over again and not learning well... If true that doesn't bode well for his future.
Don't get me wrong, he's got a good shot to make it because we have a weak, young WR corps. But this is his third year from a previous regime and he is by no means a lock.
