Over the past few weeks we examined the Ducks, position-by-position, evaluating the talent. But since I was in Eugene last week for the NCAA Track & Field Championships, I figured I'd stop by the football offices to check in with one of the guys who knows that information best, offensive coordinator Scott Frost. Today, we'll go through quarterback and running back highlights. Tomorrow, we'll get to wide receiver, tight end and the offensive line.

QUARTERBACK

Fun note: Frost lauded Mariota for being good at many different things, but apparently golf is not one of those things.

On whether the flip side of having such a great QB like Mariota is the fact that you do get attrition with other guys: "Quarterbacks are a unique breed. … They're the leaders. They're used to being the guy. It's tough for guys to come in and not play. We've had a great one, which is a good problem to have. But a lot of the guys behind him hadn't had the chance to play as much as they'd like."

Regarding last season's backup, Frost said that they felt comfortable with both Lockie and Jake Rodrigues , who has transferred to San Diego State, but if they would've had to name a backup, it would've been Lockie. But that the coaching really didn't want to "finalize the outcome of that competition until a point in time when we [needed] to."

As far as the quarterback-not-named-Mariota situation, redshirt sophomore Jeff Lockie is the No. 2 guy this season ("without question," Frost said.). Frost doesn't seem concerned that the only backups on the roster at this point are Lockie and redshirt freshman Taylor Alie . Lockie was 8-of-13 last season for 57 yards and one interception. Alie is a local walk-on, but Frost did note how impressed he was with Alie's spring.

I was curious about Mariota's injury situation -- a lot of times when guys come back there might be some hesitation or some ounce of doubt still in their minds about their knee, or ankle or whatever. Frost isn't worried about it. He said that even a few weeks after the injury Mariota wanted to get the knee brace off. Frost also said that Mariota would've run for 200 yards in the bowl game (he rushed for 133 yards) but he was out of shape from the injury.

They're certainly not shying away from any Heisman hype at this point in the year. On quarterback Marcus Mariota , Frost said, "We certainly think we have the best one in the country" and that "he throws better than anyone in the country." Well Jameis Winston , there you have it.

RUNNING BACK

On the Thomas Tyner vs. Byron Marshall debate -- Frost said there's a lot of confidence in both players. He said that it took Tyner a while to really get up to speed, but that he's there now and that Frost likes the competition between these two. Seems like even if there is a lead back and a No. 2 back, there really might not be a ton of separation in reps or carries.

Both have really good hands, but Frost said both "need to work on running routes a little bit and making sure they know more than one spot."

The first non-Tyner-Marshall player that Frost brought up was incoming freshman Tony James. James is the No. 14 RB in the 2014 class and chose the Ducks over offers from Auburn, Florida State and Ohio State.

On how the Bralon Addison injury affects the running backs: "We'd be silly if we just leave one running back on the field and most of these guys off the field. I can see us playing with more than one, using them in some other roles.

Frost cited the 2011 season when the Ducks used LaMichael James, De'Anthony Thomas and Kenjon Barner together a lot, saying that might be something we see this season. That season James rushed for 1,805 yards, Thomas rushed for 595 and Barner rushed for 939. I don't think Frost is saying that 2014 will necessarily be another 4,000-rushing yard season, but, this idea of multiple-back situations keeps coming up a lot.

Apparently, Chip Kelly used to use, what he called, the "taser" position -- a guy that can play tailback, flanker and slot. This is something they're looking at using more of next season with Tyner or Marshall, it sounds like. Even if Addison weren't injured, this would've been something they would've considered doing more of this year.
