I was the OP. I started this thread to provide a basis for discussion. IMO, it matters what it will cost to tag Cassel in 2009. In September people were throwing out $10 million as the number. $14.6 is a good deal higher than $10 million. If it is $15.3 million, that would be more than 50% higher than the early estimate.
I have tried to point out that the Patriots may be constrained by the cap. There are 12 players (Wilfork, Mankins, Watson, Ghost, O'Callaghan, Thomas, LeKevin Smith, Hobbs, Kaczur, Green, Hochstein, Yates) on the Patriots whose 2009 salaries could be increased because of attained escalators.
Please note that the 1st day of free agency is also the first day that Cassel can be traded so it is possible that the Pats could be constrained. They would not be if trades were allowed to take place before free agency started. There was talk of allowing trades to take place before free agency commenced. But as of now, that is not true.
