One guy that I've been really impressed with Datone Jones out of UCLA. He's been simply owning any of the linemen he's been facing in practice and has an extremely quick first step.

The problem is that the Chiefs would have to take him with their 2nd (assuming he makes it past Baltimore or New England) and the Chiefs probably have bigger needs at that point than a pass rushing DE (though they have jack and shit in the department currently).
