I don't know. Kahn took over the Jags in January 2012 and Tebow was traded in March. I assume that he supported the attempt to get Tebow, but whether the story that Tebow nixed the deal is an excuse or has basis in fact is up in the air. I know that Jacksonville has been on record as not being interested in Tebow now since the trade rumors started up again a few months ago.
According to Jay Glazer (Fox NFL Insider) who has excellent sources. Said on his tweeter account that Tebow chose the Jets because he knew the former HC Mularky and GM Smith was against the idea that Khan was pushing for his services. Jets had better equity at the time to make such a deal. Woody wanted to take away the headlines from the Giants who had recently won the Super Bowl. Woody did the same thing in acquiring Favre from Green Bay (after the Giants beat the Patriots in Super Bowl XLII)
Glazer went on to say this morning that It’s hard to do business with Tebow. The constant pressure of coaches to play him and the circus that follows him. Plus Tim is stubborn, if he can acquiesce to play another position then there may be a ball club or two that’ll pick him up.
Fast forward to earlier this year. Khan hires a new GM and coach. Second GM is against the idea. Went as far as saying “I can’t imagine a scenario where we could get Tim.” added “Even if he is released.” Khan may be the owner, he is not a football person so he did the right thing and yielded to his current think tank.
