With signing day just around the corner, we've been breaking down where Big 12 teams have the biggest positional need on their rosters -- and how those Big 12 teams are addressing that need in recruiting.

We finish up this series with the West Virginia Mountaineers:

Position of need: Offensive line

Who they're losing: One of the top centers in the country and two other quality starters.

Offensive line was among the strengths of West Virginia's 10-3 squad last season. And all-Big 12 center Tyler Orlosky was a big reason why.

With Orlosky leading the charge, West Virginia had four different backs rush for more than 100 yards in a game, including Justin Crawford, who became the Big 12 Offensive Newcomer of the Year.

Flanking Orlosky on the left side, Adam Pankey was a versatile three-year starter and honorable-mention All-Big 12 pick as a senior. Guard Tony Matteo also was a solid blocker as a senior starter for the Mountaineers.

Thanks in large part to this group, West Virginia led the Big 12 with an average of 5.5 yards per carry on the ground in conference, and gave up the third-fewest sacks in the league.

Who they're getting: Last year, Dana Holgorsen added Joe Wickline as his offensive line coach. This year, Holgorsen is bringing in Wickline's son to play on the same offensive line.

Kelby Wickline, arriving via Jones County (Mississippi) Junior College, is rated the No. 47 juco prospect in the country as well as the seventh-best juco offensive tackle. He carried offers from the likes of Missouri, Arkansas, Arizona State, North Carolina and Oklahoma State, where his father coached previously, before choosing West Virginia.

At 6-foot- and 280 pounds, with plenty of polish for a juco transfer, Wickline could immediately step into Pankey's role.

This week, West Virginia also picked up a commitment from Isaiah Hardy, who selected the Mountaineers over Missouri. Hardy hails from Lackawanna College in Pennsylvania, which has become a prolific recruiting pipeline for West Virginia in recent years. At 6-foot-6 and 345 pounds, Hardy carries the potential to become a road grader.

Three-star offensive tackle Tyler Thurmond rounds out this group. Thanks to the juco haul, the Mountaineers will have the luxury of letting Thurmond develop.

Because of the players they lost, the Mountaineers will have a difficult time replicating their production on the offensive line. But if Wickline can man one of the open starting spots and Hardy can shore up the depth elsewhere, West Virginia will feature another solid group up front again in 2017.
