Former USC quarterback Matt Barkley, Florida defensive tackle Sharrif Floyd, Brigham Young linebacker Ziggy Ansah and Alabama cornerback Dee Milliner are among the big-name draft prospects visiting the Browns today and Tuesday. league sources have told The Plain Dealer.

Also visiting today is former Oregon offensive lineman Kyle Long, the son of Hall of Fame defensive end Howie Long and brother of Rams former No. 2 overall pick Chris Long.

Barkley is one of many top quarterback prospects the Browns have scouted thoroughly in anticipation of the draft, April 25-27th. They've also privately worked out West Virginia's Geno Smith, Florida State's E.J. Manuel and Syracuse's Ryan Nassib.

Barkley tweeted this morning that he's headed for visits with the Browns, who have the No. 6 overall pick, and the Bills, who pick eighth.

Browns offensive coordinator Norv Turner also attended Barkley's Pro Day at USC and said he came away impressed. Former NFL quarterback Chris Weinke, who has helped Barkley and Smith prepare for the NFL Combine and their Pro Days at the IMG Academy in Florida, predicts that Barkley will be the first quarterback taken in the draft.

Barkley, who is coming off a shoulder injury, thinks that's just how it should be.

"I think there’s always something to prove,'' he said at the NFL Combine in February. "I think you’re always looking for ways to better yourself. At this point in my career, there’s definitely things I can improve on. There’s always something to improve. It seems right now that I’m kind of working my way up as opposed to already being on the top, which is a position – I’ve been in both cases before. There’s always something to prove, and I’m out to prove something.''
