This could be Alvin's last year as a Saint and it would be a massive mistake by Allen
The Alvin situation is totally flexible for a simple reason -- if Kubiak succeeds, and he proves he is the indispensable lynchpin to the Kubiak offense, and Alvin is thriving ... he's not going anywhere. He puts up 1400 total yards and he's here like Cam Jordan for another few years.
If the offense doesn't work or Alvin isn't a star in it, he's gone.
