Here's the scouting report on MB over the last year compared to the rest of MLS.

He has very strong passing numbers - and they arent just side to side passes, he's very good at progressive passes and passes into the final third.
His defensive numbers leave a bit to be desired - although he is good at successful recoveries, his number of recovery attempts is quite low.
The players he's compared to are also quite good as well. Although, nearly all of them are paid less than Bradley. It's also not Bradley's fault that he's getting paid what he is.
