i actually like this. He has been the Pats WR coach for 10 years now, and was expected to be their OC until McDaniels came back from Belichicking Indy. I'm sure O'Shea will be fired up to show his worth, and being able to use Caldwell as a resource is very exciting.
I watched an interview with him a few weeks ago where he was asked about how he feels about skill position players and getting players that fit into his offense. His response was "our goal as an offensive is to put all of our skill position players in the best place to succeed and utilize their advantages as individuals"
That to me speaks volumes. It tells me that, a lot like the "Patriots way", we are going to work on exploiting weaknesses and advantages on a game by game basis, and figure out our best matchup as opposed to putting in a "system" and hoping it works.
