The 49ers worked out two athletic SMU offensive line prospects this week, center Evan Brown and Mason Gentry, who is converting from the defensive line.
Brown fits the mold of the athletic center the 49ers have been interested in this offseason. At SMU's pro day last week, he posted a 36-inch vertical leap and a 4.97-second 40-yard dash while also putting up 36 repetitions of 225 pounds on the bench press.
San Francisco signed Weston Richburg to a big free-agent contract last month, but that hasn't dimmed their interest in centers. They are scheduled to host Iowa's James Daniels, another fleet-footed player at the position, later this month.
Like Richburg and Daniels, SMU's Brown also has experience at guard.
Gentry, meanwhile, also showed nice athleticism at the school's pro day with a 5.14-second 40-yard dash to go with 28 repetitions on the bench press. Gentry played defensive tackle for the Mustangs, but at 6-6, 310 pounds there's a belief that he'll be better suited at guard in the NFL.
A former baseball player who didn't take up football until his senior year in high school, Gentry has been working on his technique in the Atlanta area with former NFL offensive lineman John Stinchcomb and Willie Anderson and he reportedly looked sharp during position drills last week.
