Odell Beckham Jr. is about the only free agent left on the market that could actually make a big impact on a team that signs him. He is only still on the market because he is rehabbing from a torn ACL in the Super Bowl. If you have any doubt that he can still play, go back and watch the Super Bowl.
Jeremy Fowler of ESPN wrote an article listing the teams that have the best chance of signing ODB whenever he is healthy enough to play - probably sometime in mid-November. The Los Angeles Rams are unsurprisingly at the top of the list.
