There was a nice article linked to his spot with the team and playing at left tackle. While Beachum was out he was in with the first team. The guy is 6' 9" tall and about 338 lean looking pounds. He was playing at tight end and seems to be quick. A quote from the article follows.
As Villanueva walked off the practice field Tuesday with Mike Munchak, he was listening intently to his position coach. The Steelers' second-year offensive line coach played a big part in Pittsburgh's offensive success in 2014 and Villanueva has been soaking up knowledge since.
Encouraging words from Munchak and teammates like Foster have Villanueva confident that he can make it.

If this kid does come in and become the new left tackle because he is an upgrade that is a huge win for the team. Kelvin could play another position or remain the back up he was drafted to be. And that would mean the back up would be a capable left tackle, that is a huge plus. If not Villanueva could be the backup along the line or tackle. Great place to be in finding what could become a franchise tackle for nothing!
