Shelton caught a 40-yard pass over the middle from Kyle Reid and Lataimua broke off a 50-yard run down the right sideline in the 18-play situational scrimmage featuring nine third-and-two plays and nine more plays on third down and five.
"I really liked the tempo on both sides. It was physical and it was competitive, which is what we wanted it to be," said 11th-year Mustang head coach Tim Walsh. "The execution wasn't brilliant, but there were some really good things out there.
"The offense got 10 first downs and that's a pretty good deal for them," Walsh added. "We have to pride ourselves on third down as an offense and, defensively, we preach getting off the field when we get an opportunity to get off the field."
The four-week Spring Camp opened April 3 and the 15 practice sessions will culminate with the annual Spring Game, slated for Saturday, April 27, at 1 p.m. at Doerr Family Field.
Walsh said another scrimmage will be held toward the end of Saturday's practice session at about 11:45 a.m.
"There were some good things by the ones, twos and threes, and we played a lot of guys, probably 60 to 65 guys played in today's scrimmage," Walsh said. "Now we're looking forward to what we do in Saturday's scrimmage when we double it to 36 to 40 plays.
"Certain positions have definitely progressed, but there are still some positions that need to continue to improve," Walsh added. "Some of the battles have to start separating themselves. Quarterback, fullback, two of the offensive linemen, rush and will linebackers -- and a lot of backup positions that guys are fighting for – those guys need to start separating themselves and get into the mix."
Walsh particularly likes the progress of the young group of slot backs this spring.
"No doubt there are a lot of slots -- J'uan Campbell, Lepi Lataimua, CJ Cole – who have stood out and have done outstanding jobs," said Walsh. "They've done some eye-opening stuff. All the slots have gotten better, but those three guys really stick out.
"I feel comfortable about a lot of things, but there are some positions we need to get better at and we need to really get some separation on who's who between the ones and the twos."
