The Giants will trade either Engram, Janoris, or possibly Shepard to the Patriots for the 64th pick. Other pieces may also be involved (maybe even Lauletta). I think Engram would be the most likely.
Just spitballing here, but the Patriots have been in the market for a TE and slot receiver with not much to show for it so far (off the top of my head, maybe I missed something) and they can always use another CB. On top of that, they have a ton of draft picks, so it's smart for them to sacrifice some of that draft stock for a quality veteran who can help them get back to the Super Bowl for the 4th year in a row.
The Patriots have the 56th, 64th, and 73d pick in the draft, so giving up one of those three picks wouldn't be such a bitter pill to swallow. The 64th pick is in a key spot because I anticipate a major run on interior OL in the 3rd round and it's better to be at the beginning of a run than at the end of it (which is what the 95th pick represents). Someone like Deiter has a good chance of being available with the 64th pick, but not such a good chance of being available with the 95th pick.
And Deiter would be a great young addition to the OL. He can play OG at a high level, ORT at a serviceable level, and ultimately be the team's starting OC (as I see it).
