CLEVELAND, Ohio -- Two weeks ago, it was quarterback workout week for the Browns. This week, it's QB visit week.

All four of the top quarterback prospects will visit the Browns beginning this week as part of their 30 official pre-draft visits.

Oklahoma's Baker Mayfield, one of the most popular and debated of the bunch, kicks off the QB parade by arriving in Cleveland tonight. He'll spend Tuesday at the Browns facility in Berea meeting with team officials and coaches.

Wyoming's Josh Allen will visit Cleveland on Wednesday, and Josh Rosen will also be in this week, sources told cleveland.com. Sam Darnold will either be in this week or next, and Louisville's Lamar Jackson will be in town next week.

The Browns are narrowing their choices at quarterback, and are "very close" to settling on one.

Jackson said at the NFL Annual Meeting last week that Mayfield was 'no doubt' in the mix for the Browns at No. 1, and that they were blown away by his leadership ability when they worked him out privately at Oklahoma last week.

Mayfield will head to New York later this week for visits with the Jets at No. 3 and then the Giants at No. 2, according to the New York Daily News.

In addition to the 30 allowable visits, the Browns can host players who grew up in Cleveland or attended a nearby college, including Ohio State. Non-locals coming to visit can meet with club officials and current players and get examined medically, but not work out here.

Browns GM John Dorsey acknowledged last week that he wanted the QBs to visit consecutively so the Browns could compare them to each other. Coach Hue Jackson acknowledged that the pre-draft visits are a key component of the evaluations.

"That's another piece of information for us,'' Jackson said last week. "That's probably the last piece of the process for us to bring them to campus and have an opportunity to sit down with them in a different environment and talk through the things. But we will discuss how we all felt since the trip. But that will be the final piece for us."

He said the group was close to reaching a consensus, but that it could come down to draft night with all the moving parts and interest in the Browns' No. 1 and No. 4 picks.

"We all have a pretty good understanding of who the guys are, what they bring to the table,'' he said. "They're all very worthy candidates. They're all kind of different. But then again, we have to see what's the best fit for us.''

Jackson said he understands why everyone predicts the Browns will take Sam Darnold at No. 1.

"We all know that could happen, but it could not happen, too,'' he said. "We're open and very in the process and haven't made that decision yet and we're working towards it. But I don't think any of those things are out of the possibility."

The Browns are also hosting Rosen despite his former UCLA coach Jim Mora insisting that he's not a fit for Cleveland, which he believes is too blue-collar for the intellectual Rosen.

But Jackson and Dorsey were impressed when they worked Rosen out privately two weeks ago.

"He's really smart, he's engaging, he does want to be in Cleveland,'' said Dorsey. "After our conversations, he has no problems being in Cleveland. Again, it's one of those conversations where that story can take a life of its own but until you meet him I'm not going to get into that. I want to see the person before I make judgment on a person. That's fair, isn't it?''
