But see, that's the part of the equation that really makes no sense. They were willing to guarantee him $16M for this year and next year last year. Now, they aren't. What changed in the interim? Nothing as far as we can see. He put up his best season ever in the interim... He was always going to be 31 and 32 in those seasons...
The other interesting thing I've only heard mentioned briefly was that he signed his tender on Monday and on Tuesday his agents were in town for negotiations and it was then he made the comments (maybe because Karen caught him just after he'd heard that 2/$16 was no longer on the table.
I think what you have to look at is the situation changing moreso than the player. Since that offer was made three things have happened that I think affect the teams decision making process. One is that they now have a pretty good amount of capable WRs on the roster that were not there when the offer was made. Gronkowski also proved during last season to be a mega money player that is going to get huge money pretty soon and they may want to extend him a year early.
Another is that Welker signed his tender and gave up all his leverage. By agreeing to play for 1 year for 9.5 million what urgency does NE have to sign him for 2 or 3 years especially after he comes off a career year? They have a year to see if his body holds up and if some of these options prove to be valuable. Im sure if Chad Ochocinco wasnt so terrible Welker never would have had 1500 yards as there would have been an additional target in the offense. If Lloyd works out, and Branch/Gaffney/Ocho/etc... give a reasonable 3rd WR option, Welkers numbers fall and New England adjusts the salary offers accordingly. Thats why its probably best, especially for a guy probably leaving the prime of his career, to hold off on signing the tender. I think he had every intention of doing that as well until players starting taking to Twitter and things like that about getting on board and not thinking too much of himself. I dont get why they did that but I think it affected his decision making.
The other thing was that Colston signed a pretty crummy deal out in New Orleans. He doesnt get targeted nearly as much as Welker but hes a YAC guy in an explosive shorter pass role in the offense. Its less than Boldin made in his extension a few years back with the Ravens, who also fills a similar role. New England may see that as a market correction to the slot style WR in the league.
