TEs flash athleticism on Day 4

Note: All combine times are unofficial until the NFL releases results following the final workouts of the week.

A look at how some of the top tight ends on the board fared during NFL combine workouts.

UCLA TE Cory Harkey didn't put up great numbers, recording a 26.5-inch vertical jump and 9-foot-1 broad jump, in addition to an unofficial 5.09-second 40-yard dash. However, Harkey projects as a situational blocking tight end, so expectations weren't high. And while he didn't always field the ball cleanly, he helped himself by catching everything thrown at him.

LSU TE Deangelo Peterson looks explosive and got down the line quickly during the gauntlet receiving drill, but he also dropped two passes. Northwestern TE Drake Dunsmore drifted a little too much and even stumbled early on in his first run through the gauntlet, but he regained his composure and caught every pass.

Clemson TE Dwayne Allen and Georgia TE Orson Charles -- who are jockeying with Stanford's Coby Fleener for position on the tight end board -- both appeared confused and struggled in their first run though the gauntlet. They looked far smoother and caught everything the second time through. Charles did have a deep pass bounce off his hands later on in drills, however.

Allen (6-foot-3⅛, 255 pounds) wasn't as explosive as Charles, but he still moved well for his size. He also showed he is a more fundamentally sound run-blocker than Charles during one drill. Allen did a better job of rolling his hips and locking out, and while both got good hand placement and played with a wide base it was Charles who leaned into the block.

Oklahoma TE James Hanna (6-3¾, 252) turned some heads with a strong workout. Hanna posted a 4.42-second 40-yard dash, a 36-inch vertical jump and a 10-foot-2 broad jump. He did drop two passes early on, but Hanna regained his composure and fared better as drills progressed.

Missouri TE Michael Egnew is another talented athlete who also has some concerns in terms of ball skills. Egnew's 40 time was 4.53 and he tied three other players for the best vertical (36 inches) and broad jump (10-11) among tight ends, but he let the ball into his frame too much when catching passes.
