Camp is closed and half the preseason is behind us. With the idea that it’s never too early to judge in mind, here are the five things on my mind concerning the 2010 Colts thus far.

1.) Same story with the offensive line

This photo sums up how the Colts run blocking has looked so far this preseason.

The Colts can’t run. It’s hard to when your running back is draped with defenders behind the line of scrimmage.

It’s easy to point to the absence of Charlie Johnson and Jeff Saturday as the reason, but let’s face it – Johnson is an average left tackle and Saturday is 35 and has had injury issues in two of the past three preseasons.

One has to wonder if putting together a formidable patchwork offensive line will be as easy for the Colts to do as it has been in the past with Howard Mudd leading the unit.

The Colts desperately need former second-round picks Tony Ugoh and Mike Pollak to step up – so far they haven’t been impressive.

2.) Defensive continuity

Stability at outside linebacker should be a welcome sight for Colts fans.

Aside from third-round pick Kevin Thomas (cornerback) and a couple of fringe players, the Colts defense has suffered no setbacks this offseason.

All 11 defensive Super Bowl starters return to the roster. Yes, the unit got carved by Drew Brees and company in the second half, but Dwight Freeney and Jerraud Powers are healthy and Bob Sanders is back – three things the Colts didn’t have going for them in February.

The defensive tackle and outside linebacker positions are typically a turnstile on this roster, but not this year. Tackles Daniel Muir and Antonio Johnson and OLBs Clint Session and Philip Wheeler all return.

Outside of a pair of big plays surrendered against the Bills, the defense has looked solid.

3.) Lack of depth at cornerback, defensive line

Gone are Raheem Brock, Marlin Jackson and Tim Jennings.

Many would say the Colts are better off without Jennings and Jackson (who is an injury waiting to happen), but with their third-round pick shelved the Colts have some serious depth issues at corner.

The team brought in veteran Deshea Townsend. But he will be 35 in September and the Steelers let him walk when they could have signed him on the cheap – which makes you wonder.

On the defensive line the loss of Brock will take its toll. Eric Foster – who can play end or tackle – is really the only proven backup on the defensive line to speak of.

Jerry Hughes may prove to be an effective pass rusher in this league someday, but so far he looks like you’d expect – a rookie pass rusher from TCU going up against 300-pound offensive tackles.

The Colts will need former second-round pick Fili Moala (now in his second year), to step up. So far in the preseason he looks much improved.

4.) Weapons galore for Manning

Collie and Garcon were question marks coming into the '09 season - not anymore.

Peyton Manning has more weapons at his disposal than he’s had in years – 2004 to be exact when the Colts featured Marvin Harrison, Reggie Wayne, Brandon Stokley, Dallas Clark, Marcus Pollard, Edgerrin James, and Dominic Rhodes.

Wayne and Clark still among the league’s elite, Pierre Garcon and Austin Collie are the real deal and Anthony Gonzalez is back. There is no doubt the Colts’ receiving corps will cause fits for opposing secondaries.

Additionally, rookie Brody Eldridge (fifth round) is proving to be more than a blocking tight end and has been a big bright spot for the Colts this preseason.

In the backfield Joseph Addai has broken off a couple impressive touchdown runs this preseason and highly motivated (contract year), while Donald Brown is proving to be a solid No. 2 (for now).

5.) Enough about Curtis Painter

Manning has been in the NFL for a dozen years. Quick, name a decent backup that has played behind him during that time.

There isn’t one.

If Manning goes down for a significant amount of time, the season is over … it doesn’t matter who the backup is.

If Manning goes down short-term, Painter may get his shot or they may bring in a veteran.

Either way, do we really need a column from the Indy Star ever other week telling us how bad Painter is?
