No team wanted Oz.  PERIOD.  There were even reports that Browns were willing to pay most of his $16 million salary if another team was just willing to offer any draft pick.  No takers.
Just think of this for a minute.  Browns - the lowly Browns - decided to pay Oz 16 million dollars to NOT PLAY for them (and it is not like the Browns have a proven QB such as Brady, Carr or even an Alex Smith on their roster).  The Browns are paying him one way or the other.  They could have kept him as a backup QB on the roster to get some value for the money.  But they said it was better not to let Oz anywhere near their training facility (and they are paying him 16 million dollars to stay away).
You appear to be very good with stats.  Show me in NFL history where a team paid another player 16 million dollars not to play for them.
