Insider: Observations from week 2 of Colts OTAs

It's week two of OTAs (organized team activities) at Indianapolis Colts headquarters, so that means there's more to share.

Reporters are permitted to watch roughly one practice per week during OTAs, which provides at least a glimpse of how things are shaping up through the offseason.

Here's a recap of what we learned during this week's media viewing:

• Rookie to watch: Clayton Geathers

Fourth-round pick Clayton Geathers, a safety from Central Florida, could find his way onto the field this season even if veteran Dwight Lowery beats him out for the starting job at free safety.

It's evident the Colts want to take a long look at this young man based on how many snaps Geathers is getting in practices — some with the first unit.

"We're playing him down in the box in sub-packages as a dime (line)backer," Colts coach Chuck Pagano said. "So, he's learning the back end plus he's learning the sub (package). He's been really impressive as far as picking things up… He's going to be one of those guys that in today's football you can play inside as a dime backer and get faster, get more speed on the field and match up with the tight ends that we've got to cover now."

Pagano added that Geathers has "exceeded our expectations."

This is an intriguing development. For one, it's a good sign the Colts are going to make use of a unique individual talent. That's certainly a positive. And, further, it's an example of the Colts adjusting to the ever-evolving offensive trends we see in today's game. If the Colts can get this right, they might create some real problems for opponents.

• Jack Mewhort to right tackle?

When Jack Mewhort, the Colts' starter at left guard last season, was seen lining up at right tackle last week, it raised eyebrows. When we saw it again Wednesday, it was more a confirmation than a curiosity.

The Colts maintain that nothing is etched in stone. And things rarely are at this point of the offseason. But, at the very least, Mewhort sure looks like the team's contingency plan at right tackle, where doubts about the health of Gosder Cherilus persist.

Cherilus isn't likely to participate in offseason workouts after undergoing a knee procedure and dealing with other assorted injuries that severely restricted him last season. Questions about his prognosis haven't generated optimistic responses, so we have to assume there are some legitimate concerns about Cherilus in the long term.

Watching Mewhort line up at right tackle for the second straight week is just more evidence to that effect. Mewhort is slowed by an undisclosed injury, so he isn't participating in full-speed drills. But when he's been in the lineup – at least during two practices that have been open to reporters – he's been exclusively at right tackle.

• Center remains unsettled

Stop me if you've heard this before: The Colts don't know who their starting center will be.

The only difference between 2014 and 2015 is that A.Q. Shipley, who has signed with the Arizona Cardinals, is out of the picture. That leaves Khaled Holmes and Jon Harrison to fight things out. Last week, in the first practice open to media, Harrison appeared to take the lion's share of the first-unit snaps. This week, it was Holmes doing so.

Right now, it seems the revolving door of starters we saw last season might still be spinning. So, in summary, here's what we know about the center spot after two weeks of OTAs: not much.

• So many receivers, so few footballs

Let's go out on a limb and make a bold prediction: The Colts will throw for a ton of yards this season.

If you've been paying attention, you realize that's hardly a bold statement. But watching them spread the ball around in practice, it reminds you just how prolific this offense has a chance to be. There were plays on Wednesday during which T.Y. Hilton was on the sideline, while the Colts trotted out Andre Johnson, Phillip Dorsett and Donte Moncrief. Once Hilton got his breather, the Colts could come right back with another lineup that proved just as lethal, mixing Duron Carter into a number of different lineup combinations. Same thing when Johnson or others take a play off here and there.

Nothing is ever as easy as it appears in OTAs, when players can't tackle and don't wear full pads. But the small window we've been afforded is quite the tease about what might be coming down the road. And with Frank Gore lining up in the backfield, giving defenses something to think about before the ball ever leaves Andrew Luck's hand, these receivers are bound to enjoy some pretty favorable matchups.

Another thing that appears evident: Offensive coordinator Pep Hamilton is going to try to get lots of guys involved. You can tell just based on how he's mixing and matching various combinations with the first-team offense. This will make it tough on defenses to get a true read on what's coming because the personnel can change so frequently.

So, I'm sticking with my not-so-bold prediction: The Colts will throw for a ton of yards this season.
