He's bluffing. Even with his potential skills, sitting out an entire year will cause him to be drafted LOWER in next years draft. No one will want to deal with that kind of headache during the contract negotiations. ALL of this could be easily avoided by implementing a rookie cap. Players are signed relatively cheap and in camp on time; fans and owners are happy. Make it a short rookie contract- say two years then a new deal is done with an option for a third year, but then they are RFA's and can get offer sheets from other teams. NFLPA will probably never approve this during the new CBA negotiations though. But it's a pipedream of mine to see teams in the top five actually have those spots coveted by other teams for trade ups, not being stuck with taking a player in a spot they don't want to because of the rookies upcoming bloated contract. In some ways these days having a top five pick seems like a curse more than anything.
