Tim Tebow's arrival in New York already has upset one New York Jets quarterback -- Drew Stanton. The veteran backup, who signed a one-year, $1.25 million contract last Friday to be the No. 2 quarterback, has asked to be traded or released, a league source confirmed to ESPN Insider Adam Schefter.Stanton is said to be unhappy because he was promised the No. 2 job and turned down more lucrative opportunities with the Tampa Bay Buccaneers and Kansas City Chiefs to play for the Jets. He received a $500,000 signing bonus, but he could have a hard time finding a new team because the backup jobs are filling up.General manager Mike Tannenbaum confirmed earlier this week that Stanton was to be Mark Sanchez's primary backup, but the Jets changed the plan when they acquired Tebow late Wednesday night in a trade with the Denver Broncos."Tim is our backup quarterback. Mark is our starter," Tannenbaum said Thursday morning on ESPN Radio's "Mike and Mike in the Morning." http://espn.go.com/new-york/nfl/stor...al-source-says
