INDIANAPOLIS (AP) — This NFL draft will be different for Indianapolis Colts president Bill Polian.

For the first time in his decade-long tenure with the Colts, he heads into the weekend with no first-round pick, no glaring team needs and no reason to masquerade his top choice.

Yet for a man who has spent nearly three decades drafting players, it will be a new experience. The league has changed the setup, going from three rounds to two on Saturday, shortening the length of time between picks and using Sunday to sift through five rounds.

The Colts' first pick isn't likely to come until late Saturday night, forcing Polian and his colleagues to spend most of Saturday watching, waiting and contemplating.

"I'll be very interested to see what happens in the third round, to see if some of the trends continue," Polian said Friday. "And there is a very definite change in the fourth round."

By then the Colts may have added a couple of new players.

Figuring out who those players are or what position they'll play is all part of the annual guessing game.

Except that this year, the stakes are lower.

When the Colts pulled a surprise trade with San Francisco in the second round last April, moving up to take left tackle Tony Ugoh, the Colts were left without a first-round pick. It's the first time since 1991 that Indy goes into the weekend with no No. 1 choice although they traded out of the first round in 2004 on draft day.

So the Colts won't select until No. 59 this year, long after the big names being bandied about — Vernon Gholston, Glenn Dorsey, Darren McFadden, Matt Ryan and Chris Long — are long gone.

But Polian seems to like it this way.

While most analysts credit him with making the right calls between Peyton Manning and Ryan Leaf and Edgerrin James and Ricky Williams in his first two years with Indy, Polian has an even better track record of culling talent in the middle rounds, late rounds and even among undrafted players. Since joining the Colts in 1998, Polian has hit big with names like Gary Brackett, Antoine Bethea and Cato June. Bethea and June have both played in the Pro Bowl.

Now, Polian has nine picks to work his magic again.

"There's always a dearth of talent at a particular position in every draft, but the truth is you have to find what you need," Polian said. "There's always good players, you just have to find them."

What do the Colts need this year? Mostly depth.

They have 20 of 22 starters back after losing guard Jake Scott to Tennessee and No. 2 tight end Ben Utecht to Cincinnati in free agency, and last year they drafted receiver Anthony Gonzalez, who could eventually be the long-term replacement for Marvin Harrison, in the first round.

Polian could hope that a tight end like Purdue's Dustin Keller or Southern Cal's Fred Davis slips down to No. 59. Or he could take someone from what he calls a deep pool of running backs.

But the most likely option for Polian may be taking another pass rusher, perhaps Purdue defensive end Cliff Avril or Auburn's Quentin Groves, who are both quick and small by NFL standards — the kind of players Tony Dungy likes in his defense.

As usual, Polian is giving few hints about who interests him.

"On defense you never have enough rush men, you never have enough corners and we could probably use another linebacker," he said.

One possibility may be signing free agent Roosevelt Colvin, a former Purdue player who was with New England last season. Polian acknowledged that was a possibility the Colts may consider following the draft.

Polian also confirmed that whoever Indy takes this weekend, they'll be heading to training camp at Rose-Hulman Institute of Technology.

This will be the 10th consecutive year the Colts have trained in Terre Haute, and Polian's announcement ends speculation that the Colts may go to another site.

"I think it is a multiyear contract," Polian said, acknowledging he was too consumed by prep work for the draft to know the details. "The facility works for us, and there's nothing we can find wrong with the facility."

The only lingering question is who the rookies will be.

"In effect, our first-round draft choice is Tony Ugoh and he's already proved he can play in the league," Polian said. "I don't anticipate moving up because of the positioning of our picks, it would be costly to move up. You just have to find the talent to help you."
