In the NFL, free agency is a perpetual motion machine. Once it gets rolling, you'd better get out of the way.
After two days of legal tampering and two more of "actual" free agency, we have seen scores of players sign contracts totaling hundreds of millions of dollars. There are a pair of MVP quarterbacks who have yet to find new homes (although we have a pretty good idea where one is headed), but we have already seen a number of big names get bigger deals to put on a new helmet.
It has been a good week to be an offensive tackle.
