He was signed as a free agent by the Philadelphia Eagles and was waived on Sept. 3, 2010. Mallett was on the practice squads of the Eagles and Cleveland Browns last year.

Ndukwe, 6-3 and 350 pounds, has played in 33 regular season NFL games with 18 starts and two postseason games with one start. He joined the league as a rookie free agent with New Orleans in 2005. He spent time with Washington (2005-06), Baltimore (2006-07) and Miami (2007-08) before being traded to Kansas City on Aug. 24, 2009. That year he played in 12 games, with three starts at right tackle. Ndukwe was cut on Sept. 4, 2010.

Okpokowuruk, 6-3 and 250 pounds, was on the Giants' practice squad for the last two weeks of the 2010 season. He was originally signed as a rookie free agent by the Giants on April 25, 2010. Okpokowuruk was waived on July 30.

Former Giants QB coach, Chris Palmer had this to say.

"Ryan reminds me an awful lot of (Cowboys quarterback) Tony Romo," Palmer, who coached Romo in Dallas, said in an interview with NewsTimes.com last year. "But we have to re-invent Ryan. From a talent standpoint, there's no reason he shouldn't have been drafted. There's either a past history or a perception that needs to be changed. And if those things change, his phone will be very busy come November."

Perrilloux (6-2, 213 pounds) played two seasons at LSU but transferred to Jacksonville State after being kicked off the team because of unspecified violations. (Reports at the time indicated Perrilloux missed classes, meetings and workouts and also failed a drug test.)

Perrilloux, who replaces Rhett Bomar as the third quarterback on the Giants' roster, was suspended again in 2009 but came back to throw for 961 yards, 12 touchdowns and only one interception. He went undrafted last year and spent last season with the Hartford Colonials of the UFL, where he was coached by former Giants quarterbacks coach Chris Palmer, whom the Giants likely consulted on this signing.

I wondered what Perrilloux was up to then I saw he was playing in the UFL. He was the #1 recruit out of H.S. He's a talented player thats for sure. Not sure he has a chance starting at this level but I think he could be a good back up with some time. Its nice to see Palmer put a good word in for him.

Read on one draft site that he would be comparable to Donavan McNabb in the pros and Chris Palmer says Romo like.
Not too bad to be compared to I guess.
Not saying he will be though.

If Perrilloux can stick on the scout team then he gives the giants defense a legitimate quicker qb to practice against. If those two are who we compare him to.
