I can't see Bucky proving himself this year to be anything but a backup if he is only playing backup minutes. The only way he plays starting minutes is if Mason gets injured or is doodoo. If the latter, we are in trouble.
In reading the tea leaves and entrails, I think this is both sides way of saying they want to move on after this year.
The Jets see Comrie as their new hope for the future, but he needs at least another year on the Moose. I think Bucky is unhappy going into the season as the backup. He realizes that Mason is not getting that contract with the intent that he has to compete for the #1 job. The overpayment is the Jets way of getting his nose somewhat back in joint while they wait for Comrie.
If Comrie doesn't progress as hoped, I see the Jets turning to trade or free agency to get a veteran backup. Bucky will be moved if there is a decent deal to be had, or allowed to walk.
Mark my words, or fire up the crow pot.
