He kinda did:

The Seahawks tight end sent new Patriots defensive lineman Akiem Hicks a message on Twitter congratulating him on his trade out of New Orleans.
“feel blessed u got out of there,” Graham wrote to Hicks.

Graham quickly deleted the message, but it was screen-captured by Christopher Dabe of the New Orleans Times-Picayune, proving yet again that the Internet is forever.

I pointed that very tweet out earlier in my response. And I agree with Graham that Hicks should have felt blessed getting away from that mess created by Rob Ryan. Yet, if that's the worst that Graham did (and it is) then it is pretty trivial.

You’re assuming it was a dig on Rob Ryan (not even his coach). I assume it was a dig on the team that dealt him without warning. And dealt him to a team who’s players talked major pregame trash on the field to him and subsequently shut him down.

Yeah. That tweet was a jab at Payton. Hence the delete.

No, the delete was probably the conscience of a young man who most likely felt his message would be misconstrued by persons always looking for the worst in people.

And what does Ryan not being Graham's coach have to do with anything? Hicks was a square peg in a round hole in Ryan's crappy defensive scheme. Graham could see that as easily as anyone.
