Cromartie to Cowboys? It doesn't add up

This rumor about the Chargers shopping cornerback Antonio Cromartie was confirmed by Chris Mortensen today.

San Diego wants a running back and, yes, the Cowboys have three quality ones, including starter Marion Barber.

But if the Chargers want Barber, they would have to pay him $4 million in guaranteed roster bonus money in addition to a base salary of $3.8 million for 2010. That's a lot of money for a player who hasn't stayed healthy since becoming the full-time starter in 2008 and has never had a 1000-yard season.

San Diego could rework the contract, at least the base salary.

Now, say the Cowboys give up Tashard Choice.

Ben Dogra, Choice's agent, said last week he hasn't heard anything regarding a trade. The Cowboys' coaches like Choice's speed and ability to block on third down. And he's a more complete back than Felix Jones.

Well, the Cowboys love Jones' speed and ability to make people miss and wouldn't give up on a first-round pick so soon.

Now, to have three running backs is a bit much. It's probably too much for offensive coordinator Jason Garrett to handle. But with injuries occurring to all three backs at some point in the last two seasons, keeping all three is a benefit.

At least for right now.

Dallas' scouts are looking at running backs in the upcoming draft in case a move does happen.

Ok, so why would the Cowboys want Cromartie?

Terence Newman and Mike Jenkins are both coming off Pro Bowl seasons. Salary-wise, Newman is owed $9 million in a base salary in 2010.

Do you start Cromartie over Newman?

Do you start Cromartie over Jenkins?

Do you make Cromartie the third-down corner over Orlando Scandrick, a young player the Cowboys like and are projecting as a starter in a year or two?

A deal for Cromartie just doesn't make sense given what the Cowboys have on their roster right now.

Jerry Jones has said the team will not rest and will put forth an effort to improve, despite winning its first playoff game since 1996. But Jones said the team won't do anything rash.
