The redshirt senior let his actions do the talking in his return against Utah by running for 113 yards and a touchdown.
Tyler was suspended from team activities in July for profane comments he made to TMZ outside a Hollywood nightclub, missing the season opener against Minnesota. However, he still has no concerns about the proliferation of cameras and social media.
"I like talking," he said. "I'm just used to it."
The Trojans' leading rusher a year ago, Tyler admitted he was surprised by how effective he was against the Utes, posting his fourth career 100-plus yard effort.
"You could tell my cutting wasn't really there," he said. "That was from not practicing a lot, but I felt good. I didn't think I was going to get the ball 24 times and if I did I didn't I was going to be able to handle it, but after halftime I felt good."
Tyler felt the effects of his 24 carries, second only in his career to his 31 attempts last season in a win at Arizona, barely able to walk the last two days with bruised thighs, but bounced back to see the first reps in practice Tuesday.
Still head coach Lane Kiffin declined to name Tyler the starter even after his strong return.
"I thought Marc played well, especially for missing the majority of camp," Kiffin said. "Hopefully he'll improve on that. We haven't named a starter yet. We want to see those guys compete and see who comes out here and really wants to play."
Tyler is okay with that approach.
"I really don't have any voice to say anything right now," he said. "I'll just shut up and when they put me in play hard."
Kiffin criticized the play of the offensive line against Utah, even after paving the way for Tyler and allowing just one sack.
Marcus Martin from nearby Los Angeles (Calif.) Crenshaw stepped in to see most of the first-team reps at left guard, while massive Cleveland (Ohio) Glenville product Aundrey Walker alternated with incumbent John Martinez at right guard.
"We're going to give the young guys a shot again," Kiffin said. "We're into Week 3. Hopefully the two true freshmen can help out in there and do some things. But that's up to them, not up to us."
