However, if you ask his line mates, they will tell you all about him. They will tell you that he has been more helpful than almost anyone in this transition year from different offenses and from the loss of four starters along the line.
And because offensive line coach Frank Verducci can't conduct practices or line meetings in the off season, Wenger has become an invaluable part of the line. The Notre Dame transfer who spent four years in offensive coordinator Charlie Weis' offense knows the offense like nobody else.
Redshirt sophomore Jon Halapio is the leader of the line according to his teammates, has embraced Wenger and his insight wholeheartedly.
"He's been helping us with breaking down film," Halapio said of the invisible one. "It's a new playbook for all of us, so for him to come in, it was a real key addition to the offensive line. He's smart and knows all the plays that we don't know. It is like having Coach Verducci around."
Freshman Chaz Green shared in the praise for the invisible man.
"He has helped us from tackle to tackle… all five positions," Green said. "He knows the offense like the back of his hands. He helps us in the film room tremendously.
"He has been in the offense for quite a while now. He's an older guy. It is good to have him and what we really needed. The offense was new to us in the spring and he's really helped us clean it up in the off season so we can show up in the fall ready to go."
Jonotthan Harrison has a little bit different insight to the man with no face. Harrison finished spring as the starting center. Wenger was the center at Notre Dame before being let go with medical conditions that would not allow him to finish his career with the Fighting Irish.
Harrison understands just how hard it is to make the line calls and get the offensive line headed in the right direction on every play.
"I am impressed with the way Wenger knows this offense," Harrison said. "It will benefit our unit and the team. During this off season he got the offensive line together and went over protections and calls and everything. We feel more comfortable with the plays and will have better execution of the plays."
Wenger may be competition for Harrison in the fall and he knows it.
"No position is guaranteed, so we have no idea what is going to come out of camp," Harrison said.
The Gators were second in the Wenger sweepstakes back in 2006. He chose Notre Dame over Florida when he left Ft Lauderdale St. Thomas Aquinas. If he chose differently, things may have been much different. Who knows if he would be getting this sixth year of eligibility or if he would have had all of the health issues in the first place? Halapio says the boys do bust his chops about it.
"We do give him a hard time sometimes," Halapio said with a smile. "His friend (2010 starting Florida tackle) Marcus Gilbert was from the same high school, so we always give him a hard time about that."
