Which of the following players is most likely to be a bust?

I would have to say JaMarcus Russell, because first of all QB is the hardest position to play and transition in to the NFL. Another reason is ,because he's getting picked high for his physical abilities not as much how good he played in college.Even though physical atrributes are important that is not the only thing that you need to play QB. So I say JaMarcus Russell has the highest chance of bieng a bust since playing QB alone makes his chances high and he wasn't really that good in college.
