When it comes to KR's & PR's I do agree with the OP, and hopefully NE will be the team working from a shorter field for the most part. The battle of field position can be more of a factor than some might realize. If Maroney wasn't starting at RB I'd have him back there returning kicks, but since he is starting I wouldn't use him in that role. He's a very good kick returner though.
What's funny is the Patriots have a bunch of good KR's on the team this year. Maroney, Hobbs, Andrews, Welker, and Chad Jackson are all good returners. I've wondered about using Donte Stallworth on returns in the past, and he'd seemingly be great at it. Now that Donte's a key member of the starting offense I probably wouldn't risk it, but I wonder if he'd have more success on PR's & KR's with NE than his days in NO?
