One of the more impressive Pro Days of the year so far was held today in Iowa City, and the best Hawkeye prospect won’t even participate until next year. (DL, Adrian Clayborn)

Offensive tackle Bryan Bulaga had a good day in positional drills and had 27 bench reps, but the star of the day was tight-end Tony Moeaki. Moeaki cut almost a full tenth off his combine 40-yard dash, lowering it to 4.62. He also had a 6.98 3-cone drill and 36.5 inches.

CB Amari Spievey might have improved on his combine 40 time(4.51), depending on who you ask. We’ve heard reports anywhere from 4.47 and 4.57.

The Iowa linebackers, Pat Angerer and AJ Edds (shown chasing down Jonathan Dwyer above), both improved their 40 times, running identical 4.63 times. Angerer showed off a 39.5″ vertical, while Edds went for 36.5 inches.

Three main prospects were to show off in front of NFL Scouts today in Tennessee, but only two finished their workout. Top safety prospect Eric Berry left the workout after spraining his big toe early on in a positional drill, returning to the field in sneakers shortly there after and calling it a day. The injury isn’t serious and shouldn’t affect Berry’s draft stock.

Nose Tackle Dan Williams and running back Montario Hardesty, however, completed their workouts with no issues. Williams showed good footwork and the punch needed to fend off double teams. Hardesty participated only in positional drills, showing off some decent skills in the passing game.

Both Williams and Hardesty continue their climb up NFL Draft boards, Williams solidifying himself as the #3 DT behind Ndamukong Suh and Gerald McCoy. Hardesty is in the 2nd tier of RB’s behind CJ Spiller, Ryan Matthews, and Jahvid Best.

On a supposedly lucky St. Patrick’s Day, the Gator prospects were unlucky with the weather, as rain made for a tougher track for their Pro Day. With all the hoopla surrounding one Tim Tebow, we were much more interested in watching Joe Haden, Jermaine Cunningham, Carlos Dunlap, Brandon Spikes, Aaron Hernandez, Riley Cooper, and Maurkice Pouncey.

Joe Haden didn’t disappoint, running a 4.43 and locking up a top 16 draft pick. Haden’s 4.5 numbers at the combine worried some teams, but those concerns seem to be drying upp.

Brandon Spikes, however, ran a shockingly poor 5.02 40-yard dash. Nobody every mistook him for Patrick Willis, but this is even slower than scouts thought. His instincts and lack of false steps helps, but some teams are going to shy away.

Carlos Dunlap ran a 4.62, solidifying himself as one of the most athletic DE’s in the 2010 NFL Draft. Teams are still concerned with his motor, character, and work ethic.

Tim Tebow improved his throwing motion, but there is “still a loop… and a pause in the throwing motion” according to Michael Wright of the Florida Times-Union. Reports show a better spiral and release point.
