CLEVELAND, Ohio -- The Browns have already conducted private workouts with Texas A&M defensive end Myles Garrett, and quarterbacks Patrick Mahomes of Texas Tech and DeShone Kizer of Notre Dame, league sources have told cleveland.com.

The Browns are expected to take Garrett No. 1 overall, and the two quarterbacks, Mahomes and Kizer, are under consideration at No. 12 or with a later pick along with North Carolina's Mitch Trubisky and Clemson's Deshaun Watson.

The Browns also conducted a private workout with Clemson tight end Jordan Leggett, according to Dan Hope of the Greenville News.

They will also work out Trubisky and Watson privately, and Hue Jackson and Sashi Brown skipped their Pro Days. They also skipped DeShone Kizer's Pro Day Thursday, but Jackson attended Ohio State's Pro Day, where he talked to safety Malik Hooker.

Garrett, who established himself as a physical freak at the NFL Combine, is still apparently atop the Browns' board, and they're set to take him unless one of the quarterbacks blows them away during the pre-draft process. In addition to the private workouts, the Browns will bring the top prospects to Berea for visits.

At Garrett's workout and during his interviews with the Browns, he had to answer questions about apparently taking plays off last season. Garrett was battling a high ankle sprain and didn't equal his production from the previous two seasons.

Still, he's not lacking for confidence.

"I feel like I'm the best player in the draft," Garrett said at the combine.

Garrett also apologized to the Browns for jokingly asking the Cowboys to trade up to draft him in a video. He said he's up for turning around the 1-15 team.

"Everybody has their down years and at any time can be turned around," Garrett said. "The Cowboys, they turned around their season in a big way, and anybody can do that. I'm going to bring some work ethic into practice and into the weight room that will change things around there and maybe be a voice of leadership that can help swing things."

As for Mahomes, one league source said he believes the Browns like him better than Kizer. Mahomes' stock has been rising and recently had a private workout with the Saints.

"I know they loved how well-prepared I was. They could tell I had really studied and knew my stuff," Mahomes told NFL.com. "And they liked the way the ball came out of my hand. They said every time they see me under center, I look better and better."

ESPN draft analyst Todd McShay covered Kizer's Pro Day live Thursday and believes he'll go in the late first round to early second. The Browns have the first (33rd overall) and 20th (52nd) picks in the second round.

"(Kizer) makes some throws that (Mitch) Trubisky and Watson cannot make,'' McShay said. "But Kizer also misses a lot of throws that typically you wouldn't see from Trubisky or Watson. I think probably he has the strongest arm. He has the biggest upside of all of these quarterbacks.''
