The 6-foot-5, 208-pound Rumph had seven catches for 121 yards last season, but battled a hamstring injury and didn't play his first game until November against Florida.
"I'm in a good position to showcase my talent," Rumph said Friday night.
The junior college transfer had seven catches for 121 yards last season when he dealt with a hamstring injury.
Rumph said he is looking to improve "my flexibility, my health, eating right and technique, things like that. Really just getting in the playbook so I can be more versatile in the offense."
Offensive line shifts continue
There was another change in the first-team offensive line on Friday.
"They're just kind of flipping guys in and out," Mason said.
"I'm getting back to 100 percent," he said Friday.
Senior offensive tackle Watts Dantzler missed practice Friday with a concussion sustained in Thursday's full pads workout.
Of a line that is replacing three starters, tailback Todd Gurley said: "It's good, but we've got some learning to do."
Quarterbacks will be on display in scrimmage
The competition for the No. 2 quarterback job gets its biggest stage so far on Saturday with the first spring scrimmage.
"Scrimmage is gameday so that's what we're going to treat it as," redshirt sophomore Faton Bauta said. "I'm pretty excited about it. I'm sure everybody is pretty excited to strap it on and go really fast."
Bauta moved into the backup spot at the end of last season. He's now competing with redshirt freshman Brice Ramsey behind Mason.
The quarterbacks may have to deal with more than just players coming off the edge.
Sanford Stadium could be soggy with rain expected, but the forecast calls for it to clear by the time the team practices in the afternoon.
"We play outside so the elements are always a factor," Bauta said.
This and that
Mason sees a difference from last year in energy that he attributes to new defensive coordinator Jeremy Pruitt. "Guys are flying around to the ball," Mason said. "That's not something you saw a lot of last year. There's a lot more effort on both sides of the ball. We're just trying to practice and preach intensity in flying to the ball."
Gurley said he's done "everything" so far in practice after missing offseason conditioning drills followed ankle and hip injuries last season. "Todd looks completely healthy out there to me," tailback Brendan Douglas said.
More than 200 high school coaches participated in the two-day clinic that wrapped up Friday.
