IMHO, Johnny Evans is a bit out of his depth (since we haven't seen him this season with Sir Alex starting a DM ahead of his 4th CB - please tune your sarcasm meters) in the EPL and tries to overcome his lack of ability with hustle and grit. In doing so, he's a danger. Stu's competitive juices that match overcame the stark realization that Evans really didn't care what it was going to take to win that tackle, including breaking Stu's leg. Discretion can be the better part of valor. Evans is not a dirty player just an out-of-control hack but he still earned his send off and Stu still took some pretty serious damage. De Jong on the other hand just flat out attacked Stu's leg in an international friendly.
