Did Biegel win the Hightower role from McMillan, who got relegated to and eventually replaced by Elandon Roberts. Vince seems to have some leg drive and a more compact body to take on linemen on a regular basis.
Van Noy and Van Ginkel have leaner, lengthier body builds, which probably benefits from having multiple role and occassionally taking on linemen. Too many snaps and injuries affected Van Noy this season. If the team makes the playoffs next season, it's probably a good idea to reduce his snaps and have a suitable back-up so he didn't have to return from injury too soon.
