Watching offensive linemen sprint!!*

INDIANAPOLIS -- If you're interested in seeing the Chicago Bears select an offensive lineman in the first round of the draft, chances are you've been glued to Saturday's workouts at Lucas Oil Stadium.

I'm not sure if what we're seeing will change anything about the top of the offensive tackle class. With any luck, none of these linemen will run another 40-yard dash in their football lives.

But it's worth noting that Oklahoma's Lane Johnson, ranked the third-best tackle and a first-round talent by Scouts Inc., ran the 40 in 4.72 seconds -- a testament to his athletic ability if nothing else. With 35 1/4-inch arms and 10 1/8-inch hands, Johnson has all of the physical measurables that NFL scouts like to see.

The fastest 40 time for an offensive lineman belongs to Terron Armstead of Arkansas-Pine Bluff, who ran a 4.71, crushing the combine record for a lineman. For what it's worth, the previous mark was set by former Green Bay Packers lineman Allen Barbre, who ran a 4.84 in 2007 but flopped as a starter in 2009.

Both Armstead and Johnson did fine on their bench press as well; Johnson managed 32 reps of 225 pounds and Armstead had 31.

The top two tackles entering the combine, according to Scouts Inc., were Texas A&M's Luke Joeckel and Central Michigan's Eric Fisher. Neither hurt themselves with their workouts. I'm not sure if we can say the same about Alabama's D.J. Fluker, who managed only 21 reps on the bench press.
