With quarterback Andrew Luck back from injury and some reinforcement on the offensive line, many expected the Indianapolis colts to be contenders. But after two games, it appears that they are 0-2 andnot very good. Losses to the Detroit Lions and Denver Broncos have revealed the team’s many weaknesses.

The secondary

Nobody expected the Colts to have a great secondary, but they have actually been dreadful. You can blame injuries. At one point in the preseason, the Colts seven best cornerbacks were all unable to play — a frightening number when you consider most teams keep just five corners.

Before the season started, the Colts seemed solid at the position with star Vontae Davis and free-agent signee Patrick Robinson as the starters, veteran Darius Butler as the slot guy and 2015 third-round pick D’Joun Smith as the fourth guy.

So far, however, Davis has yet to play, Robinson saw 31 snaps before going down to injury in Week 1, Butler (also fighting injuries) has played 15 snaps and Smith was released due to poor play and even worse self-discipline.

Instead, the Colts have been running out Anthony Cromartie (112 snaps) — a veteran retread signed off the street a few days before the opener — along with unknowns Darryl Morris (98) and Rashaan Melvin (89). Neither Morris nor Melvin were drafted and between them have been cut from NFL teams six times. Their efforts have been commendable, but predictable.

The pass rush

The Colts defense is based on the Raven’s model from about ten years ago and relies heavily on one position for its pass rush.

It has been manned by veterans Robert Mathis and Trent Cole, and — despite some flashes — neither has come close to a sack yet. That Mathis is 35 and Cole is 33 and there is no real depth behind them is worrisome.

The Colts generated almost no pressure against the Lions’ Matthew Stafford in Week 1, and (according to Pro Football Focus), Denver’s Trevor Siemian actually had better stats when the Colts blitzed him.

The only two sacks the Colts have come up with have been from much-maligned containment ’backer Erik Walden and 334-pound fan favorite defensive tackle Zach Kerr.

The offensive line

Although hardly the disaster area it was last year, Luck’s protectors need to improve. While left guard Jack Mewhort and rookie center Ryan Kelly have been very good and right guard Denzelle Good shows promise, left tackle Anthony Castanzo has been no better than ordinary, and right tackle Joe Reitz has been subpar.

He was mauled in Week 2 by Denver’s Von Miller.

The receivers

Donte Moncrief has played solid football, but he’s out for at least a month with a scapula injury. TY Hilton and Phillip Dorsett have essentially just run go routes with predictable results — a few long gains, but also a lot of incompletions. Behind them, and thrust into the spotlight, are return man Quan Bray and undrafted rookie Chester Rogers. Bray has caught one of two passes thrown his way (for seven yards), while Rogers has been thrown to just once with no catch. Although Moncrief is a big fellow, the healthy receivers are all listed at 186 pounds or less, and Dorsett has a reputation for fragility. The team did sign Devin Street off the Patriots’ practice squad, but how much he’ll be able to help is anyone’s guess.

The future

Although the secondary should get healthier and there are three rookie offensive linemen (Joe Haeg, Le'Raven Clark and Austin Blythe) who show promise, the prospects off the Colts pass rush or receiving corps improving this year are slim. It's likely to be a long season, with Luck throwing far too many passes as the Colts try to come from behind all year long.
