There may not be any stars who went undrafted, but valuable players are found everywhere, including after the draft. And who knows, the undrafted free agent group just might have a Vontaze Burfict in it.
What players are potential targets for the Browns? Well, here's a list of players the team should at least be looking at.
Mark Harrison is talented. He is raw, he drops some passes and he's far from perfect. But the 6'3", 230-pounder is big, strong and fast. That's a start.
Cleveland doesn't desperately need a wide receiver. However, Harrison is a potential steal as an undrafted free agent, and he's a great fit in Rob Chudzkinski's offense.
There is no reason to think Harrison would help the Browns as a rookie. Cleveland has shown the draft isn't all about immediate contributions, though, so Harrison could still be a fit.
A massive 6'5", 342-pounder, Kwame Geathers is a great fit as a nose tackle. The Browns don't have great depth at nose tackle as they transition to the 3-4 defense, and Geathers could make the roster as a backup.
Geathers struggles at time, but his physical ability is impressive. He is strong and capable of driving offensive linemen backwards. He's also surprisingly athletic, though, and he can move a little.
There wouldn't be much chance of Geathers seeing much playing time as a rookie. In a year or two, though, he could develop into a solid backup or even a starter.
T.J. Barnes played defensive tackle at Georgia Tech. T.J. Barnes was bad at defensive tackle.
So maybe he should give offensive guard a shot.
The 6'6", 369-pound Barnes is obviously massive, but he's also a great athlete. He lacked the physicality to excel on defense, but his light feet and impressive size could make him a project on offense.
Barnes is a dancing bear, demonstrating the ability to move quickly. He would obviously have to learn the technique, but he has the physical ability to play guard in the NFL.
There is no chance Barnes would be ready to play as a rookie, but the potential of a transition is intriguing.
Few people expected Tyler Bray to go undrafted. He has had some off-the-field issues and is inconsistent on the field, but he is a talented passer.
Bray has perhaps the strongest arm in the draft. He can throw the ball downfield or rocket it into tight gaps across the middle. There is no throw he can't make.
Rob Chudzinski's offense requires a quarterback who can throw deep. Bray can definitely do that, and Norv Turner is just the guy to bring along Bray's other skills and turn him into a good quarterback.
Rob Chudzinski loves tight ends, and Ryan Otten is the type of tight end he prefers. Cleveland could use some more talent at the position, and Otten would have a shot at making the roster as a rookie.
At 6'5", 230 pounds, Otten is clearly undersized. That isn't a huge issue for Chudzinski, who doesn't really care about blocking from his tight ends. What matters is Otten's ability as a receiver.
A solid athlete, Otten can stretch the field and catch the ball. He isn't great as a route-runner, but his ability to split out wide and catch the ball makes him a fit with Cleveland.
A great athlete, Jonathan Stewart has potential. The 6'4", 242-pounder isn't great right now, but his size and speed are appealing qualities.
Cleveland has one clear starting inside linebacker in D'Qwell Jackson. The other spot is much more hazy, and it's hard to say who might step in there. It probably wouldn't be Stewart, but he could be an option in the future.
Stewart is a great athlete who is at his best when playing in coverage. However, his speed and athleticism could result in him being adequate against the run in time.
Neither of the Browns' punters—Spencer Lanning and Jake Schum—has experience in the NFL. Of course, Brad Wing doesn't either, but he's considerably more talented than Lanning and Schum are.
As odd as it sounds, the only reason Wing wasn't drafted is because of character concerns. A punter with character issues, yeah, it sounds crazy.
However, Wing can really boom the ball, and he could be an above-average punter as a rookie. This is a no-risk/high-reward signing (granted, at punter).
Lawrence Okoye is one of the more interesting prospects in the 2013 NFL draft. The British track star has never actually played football. However, the 6'5", 304-pounder ran a 4.75 in the 40-yard dash and is an incredible athlete.
Of course, Okoye would need coaching and refinement. But it is hard to find players with that type of physical ability, and Okoye could eventually be a great fit in Cleveland's attacking 3-4 defense.
There is a great chance that this signing wouldn't pay off at all. However, there is the slightest chance that Okoye could be a star. Given the lack of risk, that's worth a shot.
On talent alone, Da'Rick Rogers is a first-round pick. The 6'3", 217-pounder showed great ability at Tennessee before being suspended and transferring to Tennessee Tech.
It is possible that Rogers could be a No. 1 wide receiver in the NFL. Character issues could stop that from happening, but he is talented enough to be a 1,000-yard receiver.
This is another no-risk/high-reward scenario. There is no risk in signing Rogers. But giving him a chance could pay off in a big, big way.
Kerry Rhodes is the only veteran on this list. The veteran safety has played under Ray Horton and is good in coverage. That is a perfect fit for the Browns.
Cleveland lacks a free safety to play next to T.J. Ward, and Rhodes is more than capable of filling that void. The 30-year-old had four sacks in 2012 and still showed the ability to match up with wide receivers.
At this point in his career, Rhodes may not be a star. He is still a solid starter, though, and he would address a huge need for the Browns.
