Posted on Scout.com, Calloway is apparently dropping as an OT because of his 40 time and vertical????  Who writes this shit?  Oh noes, he can't jump very high, what ever will he do?  Since when did vertical determine how well you come out of a stance and how good your technique is?  All of their posts were about how slow the lineman were lol.

Kyle Calloway, OT, Iowa

The tackle who plays opposite highly touted left tackle prospect Bryan Bulaga, Calloway (6-foot-6, 323 pounds) had a disappointing workout on Saturday. He was timed at 5.51 in the 40 and was handed the lowest vertical (23.5-inches) of all the offensive linemen.

Dace Richardson, OT, Iowa

An injury-plagued career hurt the versatile Richardson from developing into a consistent starter for Iowa, and after his performance at the Combine on Saturday, where he turned in a 5.78 in the 40, there’s no chance he will be drafted.

Ciron Black, OT, LSU

Black started 53 consecutive games at left tackle for LSU, but the 6-foot-4, 327-pounder has struggled to impress this offseason. He’s displayed slow feet, and it really showed when he ran a 5.49 in the 40. Black isn’t the most athletic tackle available in the draft, and his 25.5-inch vertical revealed his lack of explosion. Black’s stock is tumbling and he could ultimately come off the board in the fourth round.
