Five quarterbacks could go Thursday in the first round of the NFL Draft. Another one who’s far from a rookie, Aaron Rodgers, already got the call on Monday. Rodgers’ freefall in the 2005 draft is unforgettable. He slipped all the way to No. 24 — after the Bears, Raiders and several other teams made forgettable picks — and was wisely scooped up by the Packers. Rodgers and Green Bay finally have parted ways, traded to the Jets. Will one of the top quarterback prospects in this class fall out of the top 10 like Rodgers did? After the No. 1 overall pick, which seems relatively certain, it’s a draft riddled with mystery. The betting markets have been moving fast as information leaks and rumors swirl. The job of a bettor and mock drafter is to filter the rumors and see through the smokescreens while trying to make the puzzle pieces fit in a way that makes sense.
