Early this morning, Willie McGinest critical comments about Wes Welker's approach with his contract were relayed here.
Word got back to Welker, who fired back on Twitter today via Twitter:
"@williemcginest why did u ever leave the Pats and play for the Browns?"
A short time later, McGinest tweeted a reply:
"@WesWelker My point exactly. We're all expendable at Patriot Place"
McGinest did indeed leave the Patriots for the Browns as a free agent in 2006, cashing in on a three-year contract the club wasn't willing to match. He also had expressed disappointment that the Patriots would give out No. 55 (to Junior Seau) so quickly (link here).
