The Missouri Tigers have one of the deepest offensive lines in college football, returning all seven players who made starts last season.

However, two new players — redshirt freshman Trystan Castillo and sophomore Tre’Vour Simms — have worked their way into starting roles in the latest depth chart.

According to STLToday.com, Castillo has replaced Jonah Dubinski as the starting center and Simms has supplanted Adam Ploudre at right guard.

Offensive line coach Glen Elarbee said he still expects Dubinski, Ploudre and the other backups to get plenty of action throughout the season:

“As fast as we go (the depth) is a huge luxury,” Elarbee said. “You start getting to that 90, 100, 100-plus snap count, that’s a lot on a big man, especially as much as we’re asking them to do and play. Hopefully we can keep a fresh bunch in there because we see a whole new crop of D-linemen each series. We might as well see if we can match that.”

The Tigers kick off their 2017 season on Saturday, Sept. 2, by hosting Missouri State. The game starts at 11 a.m. Central time and can be seen on the SEC Network.
