There are always a number of transactions that could happen but don't in the NFL offseason, and the ones that do frequently happen as we approach the NFL Draft. Teams trade players for picks and picks for picks. ESPN's Mike Sando wrote an Insider article suggesting draft trades that should happen because they work for all teams involved. The Arizona Cardinals are involved with one.
Sando says the Cardinals should trade receiver Michael Floyd to the division rival Los Angeles Rams for one of their second round picks.
