For BB, I think this is the coaching equivalent of Michael Floyd on the waiver wire, or Randy Moss available for a mid-round draft pick. It's like the $20 bill you find in an old pair of jeans. Unexpected windfall.
How could we use Chip, given that our coaching staff is already deep and talented? Who knows. I'm guessing Belichick will wrack his brain to find a creative solution.
How about this: have Chip design a couple of "extraordinary situation" plays as a bonus addendum to the playbook... a super secret 2-pt conversion... a 6-wide gimmick play with no QB. Give Chip half a day each week to install his extraordinary situation packages, hand picked players, for emergency situations.
