To the extent that any 2012 NFL Draft prospect can have a "bad day" standing on a scale, being measured and talking to reporters, Iowa offensive tackle Riley Reiff - a pre-NFL Combine consensus Top 10 pick, and a guy that should absolutely be on the radar of Buffalo Bills fans - had a bad day on Thursday.
Offensive linemen weighed in Thursday, and Reiff became the latest Iowa lineman to measure in with shorter-than-expected arm length; he's got 33.25-inch arms attached to a 6'5", 313-pound frame. That's a number that will make scouts a bit nervous projecting Reiff to tackle in the NFL, regardless of what he looks like on tape.
This is a trend for Iowa linemen. Robert Gallery, the No. 2 overall pick in the 2004 NFL Draft, never panned out at tackle because of short arms. The same issue caused Bryan Bulaga - who many considered a potential Top 5 pick in 2010 - to fall all the way to No. 23, and now he's a right tackle.
Reiff is an excellent football player, and he's still going to be a first-round pick. Don't be shocked, however, when several teams slide Reiff down draft boards because of this development. A few may even view him as a guard.
