Orlando Brown didn't have a great Combine.

The offensive tackle from Oklahoma put up one of the worst 40-yard dash times, and the once projected first-round pick failed to do more than 14 reps in the bench press.

Brown, who was an All-American last season and helped protect Heisman winner Baker Mayfield, didn't help his draft stock in Indianapolis. His 40-yard dash time was 5.85, tied for the fifth-slowest since 2000, according to Pro Football Focus.

Afterwards, Brown talked to NFL Network. He wasn't overly disappointed, but he said he will have a chance to redeem himself at Oklahoma's Pro Day.

"The 40 is what I expected, what me and my people expected. It's something obviously I've been working on. The number was better today than it's been in the past. I'm not extremely happy with it. Not what I wanted," Brown said.

He confirmed that he would re-test on the bench and said he normally puts up 18-20 reps. He will also participate in position drills.

Mayfield, who is also at the Combine, defended his former lineman and pointed out the fact that he didn't allow one sack last season.

"When are you going to watch Orlando Brown run 40 yards down the field? Never," Mayfield said to reporters.

Brown's lack of speed is no secret. But Brown was last in most categories among the lineman. He had the worst bench press, worst vertical jump (19.5 inches) and worst broad jump (82.0).

He also showed a lack of effort in the drills, according to reports. Brown's poor performance may indicate he's not taking the time necessary to prepare. Everyone agrees that the Combine is superfluous since there's an abundance of film, pro days and workouts with teams.

But what it can expose are those who are not taking the process seriously, and teams may have a negative perception of Brown after his poor showing.

He doesn't need to run a great 40, but he needs to show improvement. Not regression.

Luckily, he's got good tape, so in the end he shouldn't fall too much.
