Mel Kiper takes Johnathan Joseph over Bobby Carpenter

MOBILE, Ala. -- ESPN NFL Draft expert Mel Kiper went back in history and redrafted the 2006 class for every team.

That year the Cowboys drafted linebacker Bobby Carpenter from Ohio State. Carpenter's claim to fame might have been that NFC wild-card playoff loss at Seattle where he played out of his mind.

Carpenter was a disappointment overall.

Kiper now says the Cowboys should have taken South Carolina cornerback Johnathan Joseph with the 18th pick. Kiper also says Houston should have bypassed Mario Williams with the top pick and selected Haloti Ngata, the defensive tackle from Oregon.

Here's a link to Kiper's selections (you need to be an ESPN Insider to view it).

We look at the Cowboys' draft picks that year:

Bobby Carpenter, first round, LB: The Cowboys could never find a role for Carpenter, whether it was at inside linebacker or outside linebacker. He just wasn't physical enough and always seemed overmatched. The best thing about Carpenter is he became one of Tony Romo's closest friends. After the Cowboys moved on from Carpenter, with a trade to St. Louis for tackle Alex Barron, he switched teams again. Carpenter played for Detroit in 2011 and picked off a Romo pass in the second half as part of the Lions' dramatic rally to overcome a 24-3 deficit.

Anthony Fasano, second round, TE: A physical tight end that just never took his game to the next level. He wasn't going to compete on Jason Witten's level, but he wasn't athletic enough, like Martellus Bennett was, to warrant more playing time. Cowboys eventually traded him to the Miami Dolphins. Fasano has been pretty good in Miami, catching 18 touchdowns in four seasons while Bennett has just four in four seasons.

Jason Hatcher, third round, DE: It took some time but Hatcher finally emerged as the pass-rushing end the Cowboys thought they had when they selected him from Grambling. Hatcher eventually took a starting role at end this season from Marcus Spears, a former first-round pick. Hatcher finished the season with a career-high 4.5 sacks. He will probably start at end in 2012. Hatcher is the only player from this draft class still on the team.

Skyler Green, fourth round, WR: Bill Parcells had plans for this man. The problem was that the plans were a mess. A returner, a wide receiver and a running back eventually, Green couldn't find any playing time. The Cowboys should have passed on him unless they had a defined role for him, and they didn't.

Patrick Watkins, fifth round, S: He started nine games his rookie season, picking off three passes and knocking down seven more. But Watkins wasn't physical enough for the defensive coaches and while a free safety had trouble making plays on the ball. He didn't play in the NFL last season after spending 2010 in San Diego. He was long and lean, very athletic, but just couldn't find consistency.

Montavious Stanley, sixth round, DT: He's bounced around among five NFL teams, including two stints with the Jacksonville Jaguars. Stanley just wasn't a fit with the Cowboys. He had the size to play inside (6-2, 302 pounds), but like most late round picks, he didn't play with the needed consistency.

Pat McQuistan, seventh round, T: He might have been a nice find to possibly replace either Flozell Adams or Marc Colombo at one of the tackle spots, but he never developed into what the Cowboys hoped. He played mainly on special teams before going to Miami in 2010. He did start eight games for the Dolphins and in 2011 he played 10 games for the New Orleans Saints.

E.J. Whitley, seventh round, G: The Texas Tech alum was the 224th player selected that year. He didn't do enough to warrant a roster spot.
