Why wasn't Auburn center Reese Dismukes picked in NFL Draft?

Reese Dismukes was selected as the nation's best center in college football last season, but it didn't earn him a spot in the NFL Draft.
In what proved to be the biggest surprise for Auburn in the draft, Dismukes was not selected in the seven rounds of the draft. He was projected as a mid-round selection by many analysts entering the draft.
The Rimington Trophy winner was a first-team All-SEC center in 2014 and was considered one of the top three centers in the draft by many analysts.
"He is the smartest offensive lineman I have ever coached, by far," Auburn offensive line coach
J.B. Grimes said. "He is a guy that will glom on to the NFL terminology and the protections and all those kind of things that we don't do (at Auburn), but he'll be a guy that will be running your whole line in no time."
Five of 16 Rimington Trophy winners were not picked in the NFL Draft.
Why did Dismukes slide out of the draft and forced to test free agency?
Concerns about Dismukes' character were voiced by teams leading up to the draft, according to WalterFootball.com.
"Sources question Dismukes' ability to fit in a locker room," according to the WalterFootball.com report. "Teams have some off-the-field concerns about him as a person, and they aren't sure that he will be a good teammate to all segments of the locker room."
Dismukes started all 50 games he appeared in and was a team captain in his final 27 starts as Auburn's leader on offense. He also paved the way to the SEC Championship in 2013, when the Tigers had the nation's top rushing offense (328.3 yards per game). He graded 90 percent or better in each start during his final two seasons with the Tigers.
Dismukes' stock took a slight hit at the Senior Bowl, but many analysts still considered him a top-tier center heading into the draft.
His hand size (the smallest of all players at the Senior Bowl) was a concern, and so was his lack of experience as a pass blocker.
"I think the biggest question they have is when a 350-pound zero nose guard lines up on him nose up and he's offsides, how does he handle it?" Grimes said. "The answer is you've got a guy who has great leverage with great hands. He's a guy that's really, really quick with his hands.
He's a guy who can tie one of those guys up. As far as getting movement, there aren't three centers in the NFL that can get movement on
Vince Wilfork. A Mack truck can't get movement on Vince Wilfork, so don't tell me that. You need a guy that can command your offensive line."
Five Auburn players were selected in the NFL Draft.
