According to Clark Judge of Cbssports.com, Rex Grossman is one of the the top ten backup quarterbacks in the NFL.

This is what Judge had to say:

“I wasn’t sold on him as Chicago’s starter, either, but a couple of things here: 1) He was good enough to make it to the Super Bowl, and 2) he’s not a starter anymore. Granted, the Bears’ defense launched them to Super Bowl XLI, not Grossman, but he had to play a role … and he did, performing so well he was named the NFC’s Offensive Player of the Month in September. Grossman makes too many mistakes and takes too many chances, but he has big-game experience and a 19-12 record as a starter. There are 12 starting quarterbacks going into training camps later this month who haven’t won as many games. I don’t know if he beats out Dan Orlovsky as the Texans’ backup, but I know he should. He is out of the eye of the storm, which is where the starter in Chicago sits, and should be comfortable backing up . As a backup a year ago, he relieved an injured Kyle Orton and produced two TDs, including the winner on a quarterback sneak. Nevertheless, he still was booed by Bears’ fans. The change of scenery should do nothing but help.”

I agree with Clark Judge, I think Grossman is one of the better quarterbacks in the NFL. He definitely has one of the best arms out of all the backups.

Other quarterbacks on the list include:

Jeff Garcia, Derek Anderson, Jon Kitna, Tyler Thigpen, Sage Rosenfels, Tavaris Jackson, Matt Leinart, Charlie Batch and Todd Collins.

One guy I thought should be on the list was David Carr, he is a much improved QB with the Giants.
