BEREA, Ohio -- Browns coach Hue Jackson wasn't ready to christen second-round pick DeShone Kizer his starting quarterback just yet.

"We're going to give all our guys an opportunity to compete,'' Jackson said. "That's what it's all about. It's not about who is the starter, who is this. Let's let these guys get here and learn our offense and spend time with myself and (quarterback coach David) Lee and go out on the field and let's see how it all turns out.''

Kizer, who tumbled out of the first round and was taken by the Browns at No. 52, will compete with Cody Kessler, Brock Osweiler, and Kevin Hogan -- for now.

But the Browns might not be done shaping their quarterback room just yet. They've expressed interest in Patriots backup Jimmy Garoppolo and Bengals quarterback AJ McCarron has been on their radar. Other veterans could become available now that teams have drafted rookies.

Browns head of football operations Sashi Brown has made it clear he'll continue to search for a QB and "won't rest until we've solidified the position.'' He said Thursday he might try to trade for a veteran or do whatever it takes to upgrade the spot.

The addition of Kizer adds to the pile, but doesn't necessarily solve the problem.

However, Jackson, who values size and a big arm, seemed genuinely pleased to have Kizer, a Toledo native, in the fold. The Notre Dame product was the fourth quarterback off the board behind first-rounders Mitch Trubisky, Patrick Mahomes and Deshaun Watson.

"I think we're better at the position," said Jackson. "I think we've made huge strides over the last several months at that position."

Kizer (6-4, 233) is the biggest of all the top prospects, and has some mobility to go along with his strong arm.

"Obviously, he has the measurables, a big, physical quarterback who can make all the throws that anybody needs to make in the National Football League,'' said Jackson. "He's intelligent. So he has the characteristics that we're looking for."

Jackson acknowledged at the NFL Combine that Kizer's 4-8 record last season was a concern. What's more, Kizer was benched in the third quarter of the Stanford game after throwing back-to-back interceptions.

"I think just through our conversations, with the conversations with us all, we did a really good job of making sure that we crossed all the T's and dotted all the I's and are very comfortable with his situation at Notre Dame,'' said Jackson.

Kizer's completion percentage also dipped from 63 percent in 2015 to 59 percent in 2016.

"It's a combination of a lot of things,'' said Jackson. "The receivers play a part in it. To DeShone's defense, he played with a lot of young receivers a year ago and I think that's difficult when you're a veteran player, but he's been very honest that he knows that's something he needs to work at."

After taking tips from Jackson and Lee during their private workout, Kizer has made adjustments in his mechanics. He'll undoubtedly also work with a quarterback guru such as Tom House to further improve.

"It helped me out quite a bit already,'' he said. "So I'm very confident that once I get to their system and I'm able to be in the facility, I believe those improvements will continue and I'll be able to become a more accurate thrower."

Scouts and draft experts were split on their evaluations of Kizer. One told NFL draft expert Nolan Nawrocki: "I see his ceiling as a backup. Someone is going to draft him expecting him to be a lot more than that. Some of our scouts have first-round grades on him. One question: When was the last time a quarterback that was benched for underperforming during the year was selected in the first round?''

NFL Network's Mike Mayock told Monday Morning quarterback, "I think he has the most upside, the highest ceiling. But he is 12-11 as a starter at Notre Dame. He played a lot of bad football with the game on the line in the fourth quarter this year. That is not acceptable.

"But he is 6-5, 235. He has that kind of prototypical franchise quarterback look, a Phillip Rivers type ... if he gets everything right."

Cardinals coach Bruce Arians said at the NFL annual meetings that only one of the draftable QBs was ready to start, and he was believed to be talking about Kizer.

"All the rest, there are some really talented arms that need a year of learning how to play the position, especially at this level," Arians said.

49ers coach Kyle Shanahan, when asked about Kizer at the league meetings, said players can improve with good coaching.

"You can improve at everything,'' he said. "As you get better in your technique, you get your feet under you more. You look at why they've had accuracy issues. I'm not talking about him specifically. But if a guy's missing throws, you look into why they're missing throws.

"You don't ever want to change a guy's throwing motion too much. That's pretty much how they throw. You don't want to mess with a guy. But you can always work with their footwork, their timing, keeping their feet under them, how to keep them to stay a passer and not get in a running position.''

Jackson likes the fact that Kizer has mobility to go along with his arm talent.

"I'm glad he has that athletic ability, but obviously we play a lot of different ways,'' he said. "You have to play from the pocket, but you also have to be able to escape defenses as you face them. ... He's very coachable. He wants to work at it, and that's what it's going to take. We'll find out how good this guy can be over time.''
