Browns holding workout with Bortles

The Cleveland Browns ramped up their evaluation of the top quarterbacks in the draft with a private workout with Central Florida's Blake Bortles, ESPN's Adam Caplan confirmed. This comes two days after the Browns brought in Derek Carr.

What's the difference between Bortles and Carr? Bortles is worthy of the No. 4 overall pick, and Carr is not.

Bortles has the size, arm strength and athleticism to become a franchise quarterback. The risk in taking him this high is the fact that it's all based on perceived potential.

Any team that takes Bortles will probably have to wait one or two years for him to develop. Patience hasn't been a strong suit of the Browns, who change quarterbacks quicker than most fantasy football league owners do.

Still, no one knows whether Bortles will be there when the Browns are on the clock or whether the Browns will take him if he's still available. ESPN.com Browns reporter Pat McManamon selected Bortles in the NFL Nation mock draft of the top five picks.

Something tells me Brian Hoyer would like that selection.
