Logan was 28 in the 2010 season when he sat out half the year. He was 29 was he was franchised (2011). He was only 7 months shy of 30 when he got his deal. Wes turned 31 less than a month ago. A year and a half separates "worth a five year deal" and "cut and run"? Guard is a way more physical job; I'd expect them to start looking old faster.

Wes Welker may not be the best WR in the game, but he's way up there. I'd argue he deserves big money (although, yes, not $120M over 8 years, that would be clinically insane). Over the last 3 years, he's been #5 in yards, #2 in receptions, and somewhere near the top in YAC.
