ORLANDO -- Many draft experts believe that the 'tastes great/less filling' debate for the Browns is between Sam Darnold and Josh Allen.

But at least one source close to the situation told cleveland.com he believes the Browns still have 'sincere interest' in Mayfield after a 'great' private workout with the Browns at Oklahoma last week and that he's still legitimately in the discussion for the Browns at No. 1, No. 4 or wherever they pick their Qb.

At the NFL Annual Meeting Monday, Browns GM John Dorsey said it's 'fair enough' to surmise that the top four quarterbacks are still in the mix: Darnold, Allen, Mayfield and Josh Rosen.

But the source said the Browns aren't just giving lip service to the Mayfield talk, and that they genuinely like him. Whether or not they'd take him No. 1 overall is still in question, but the Browns have some options in terms of trading up or down with their first two picks.

"He had a really good workout,'' said Dorsey. "He had a really good conversation with the group that night. He did really well on the Xs and Os. That determination will come I would say within the next three to four weeks of kind of where we're going to be in that process and kind of finalize everything toward the draft."

Dating back to the Senior Bowl in January, Dorsey has defended Mayfield's character and complimented his passion for the game, even if it's misguided at times.

"He's very competitive on the football field,'' said Dorsey. "His teammates absolutely love him. Everybody in the support organization of Oklahoma loves him. He's got a degree of humility in his person.''

As for Mayfield's statement at the NFL Combine earlier this month that "if anybody's going to turn that franchise around, it would be me,'' Dorsey, who was around Brett Favre and Aaron Rodgers in Green Bay, likes the moxie.

"What are these guys, millennials?'' said Dorsey. "It's a different mindset now.''

As for the autobiographical documentary being filmed on Mayfield called "Behind Baker,'' Dorsey has no problem with his celebrity status and drawing attention to himself.

"If you love the game of football and you really are a good person and you get along with your teammates, to me, the other stuff is that marketing, media,'' he said. "Would I like for him to concentrate on (football) yeah. But I mean, these guys are different platforms now. They do different things.''

With Dorsey comfortable with Mayfield's personality and face-of-the-franchise ability, the last remaining big hurdle is his 6-foot-5/8 inch height -- which is similar to that of Browns' starter Tyrod Taylor.

"Can he play the game of football well?'' Dorsey said.

Mayfield seems to be the closest scheme fit to Taylor for a seamless transition, but Dorsey dismissed that notion.

"When you have quality coaches that are really adept at that position, they're going to really find ways to put Tyrod in position, or whoever the quarterback may be in the future, and they put him in that position,'' he said. "That doesn't really bother me.''

As for the prevailing sentiment that the Browns will draft Darnold, Dorsey said, "I still say the draft is five weeks away. I know this. They're all good football players. You can't have enough of them."

The Browns already have one evaluator in their building who had Mayfield No. 1 in his QB rankings heading into the pre-draft process in consultant Scot McCloughan. Question is, do they have others? Are they all on the same page in terms of the QB they like?

"Well, I think there's great communication and really good discussions in every different phase of this thing,'' said Dorsey. "And moving forward, I will continue to hope there's that ongoing discussion and everybody sees it like mindedness. If not, let's have a discussion and talk it out.''
