Burnett is the only guy that's going to be throwing any thing close to a knucklecurveball this year, so you can't really compare him to the others guys too well. He throws harder than everyone else and gets a lot more whiffs than everyone else (which isn't represented in this data). He is a pure strikeout pitcher, which the Pirates have not had in a long time. It should fun to watch him work this year. If he can limit the home runs and take advantage of the league change, he could be a very exciting pitcher.
