Welker wasn't asking to break the bank. He went back to the Patriots to see if they would match the 2 year $12M offer, they said no. They had already moved on when he wouldn't sign their 2 year $10M offer. They then gave Amendola a 5 year deal at more money, or very similar money.
So it had nothing to do with the cap, which is the usual reason they let good players go.
can you not comprehend the actual sequence of events? They have been explained to you many, many times and yet you spread bad info.
1) Pats make Wes a final take it or leave it offer
2) Wes decides "leave it"
3a) Wes looks for a better offer & simultaneously
3b) Pats talk to Amendola, an in-demand "plan B"
4) Pats come to an agreement with Amendola
5) Wes decides his only good offer is Denver, but it's less than he wanted and, with incentives, less than the Pats take it or leave it offer
6) Wes contacts Kraft hoping for a re-do of that take it or leave it offer
7) Kraft tells him that some of his money is already spent, due to the timing, and he cannot even come up to the earlier take it or leave it offer. 2 years, 10 million is the most he can go (investing over 10 million in two slot receivers)
8) Wes becomes a Bronco
it's business, unfortunately.
Sometimes a take it or leave it offer means a take it or leave it offer, because you cannot wait for plan A to come through and put plan B at risk.
