How Does Favre Signing Affect Tarvaris Jackson, John David Booty?

Say what you will about John David Booty, he's got a memorable name. Sadly, his name what be much help as the Minnesota Vikings third string quarterback is likely out of a job thanks to the signing of Brett Favre.

With Brett Favre on the Minnesota Vikings roster, along with Sage Rosenfels and Tarvaris Jackson, it's looking like John David Booty may end up being the odd man out. Want proof? Mr. Booty has already been asked to switch his uniform number from #4 to #9 to allow Brett Favre to wear the same uniform number he's worn during his long NFL career.

With Favre on board, it looks like Sage Rosenfels will still have a job either as starter or backup. The real man at risk is Tarvaris Jackson. Jackson has struggled with injuries at training camp. Reports have circulated that Jackson is unhappy in Minnesota and may demand a trade. Pro Football Talk has even suggested that Tarvaris Jackson might move to Green Bay.
