‘Ryan Fitzpatrick’s job isn’t in jeopardy — yet — despite a 13-21 record as a starter and a league-high 23 interceptions in 2011. But one of the more interesting hypotheticals in Buffalo is who would replace Fitzpatrick should the Bills choose to pull the plug on the seven-year, $62 million contract he signed a season ago. It could be Vince Young, late of the Eagles. Or it could be Tyler Thigpen, who knows coach Chan Gailey’s system. In a camp without a lot of big position battles, this could be one of the more interesting ones to watch.’
