I could be mistaken, but I recall specifically he was recruited to play OL and they played him at DL because he was too light to play OL. I found a few mixed articles, but looks like he played both ways in HS and was recruited by many to play OL...but he wanted to play DL (good move on his part):
Here he's listed as a OT, the #45 ranked OT in the class:
Taven Bryan, Natrona County, Offensive Tackle
From an article when he committed:
Taven Bryan Commits to Florida: Gators Land Huge Athlete from Wyoming
At 6'5", 250 pounds, he has the wide frame and height to continue to develop into a monster wherever he lines up. He also has versatility, as he can stick to playing offensive line or eventually make the switch and become a defensive lineman.
According to
Luke Stampini of 247Sports, the Florida coaching staff is open to him playing a number of positions.
"He said he's going to come get me," Bryan said of Muschamp. "They want me for defensive end, [offensive] tackle, tight end and I want to play defensive end."
