There's an immediate difference in the game speed in college compared to high school.
And incoming wide receiver Kenny Stills said the same thing, but also said something else has made that transition easier for him this spring.
"It's football," Stills said. "You know what I mean? I know it's a big step from high school to college, but it's still football to me, and I've always been around football. You know, my dad played in the league, so it's just, I'm comfortable wherever it is playing ball, and that's what it was for me."
Perhaps that familiarity and the confidence in adapting to the changing game speed as quickly as possible were the reasons why Stills posted such a successful spring.
He dazzled in the Spring Game, of course, with his six-reception, 84-yard performance, which included a 31-yard touchdown grab.
So, was his outing a statement to suggest he can make a major impact next year for the Sooner wide receiving corps?
"I hope so," Stills said. "I mean, I wasn't really out there to prove anyone wrong, you know, but I was just going out there to play to the best of my ability."
Nevertheless, he excelled on that day, and because of that, it's safe to say Stills will compete for playing time and a possibly a starting spot.
One thing that he has in his favor as an incoming freshman is the trust factor with quarterback Landry Jones.
A lot of guys have trouble establishing that from the get-go, but that has not been the case with Stills.
However, he hasn't done anything special to gain that trust.
"You know, nothing actually," Stills said. "You know, I mean I'm always up to catch extra balls, but, you know, we're just getting so many reps right now just collectively as a team, so I mean all of us are working together, so I think he's pretty comfortable with everyone right now."
Another obvious thing Stills has in his favor is his explosiveness featuring a combination of speed and elusiveness that makes him very dangerous in one-on-one situations.
"Yeah, as a receiver, you ask any receiver in there or anywhere or anyway, you love one-on-one," Stills said. "You see one-on-one, and that's what you live for, so if you can't beat a guy one-on-one, then you're no good."
Another is just his maturity of knowing what to expect.
"You know, the workouts are real serious here," Stills said. "You know, I was looking forward to that. I mean, if you read anything before I came here, I was looking forward to getting in the weight room and gaining a few pounds."
So, those are a few things Stills has in his favor towards battling for playing time in 2010.
But that doesn't mean there still aren't things he's working to improve upon.
"Still the speed of the game [is challenging]," Stills said. "I mean, I can always improve on everything. You know what I mean? I'm still learning a lot in terms of the plays or, like I said, the speed or just the strength of everyone else out there, so I definitely think it's the speed of the game right now, but I feel I can still take a step forward with everything."
Coming out of the spring, though, he has made a statement that he's ready to compete.
