Bryce Harper is baseball to a new generation. There's no false modesty about him. And not enough modesty for his critics. Harper is a polarizing figure. This point was driven home again Thursday night when the Cubs threw at him, creating a brief dust-up between the clubs. The Cubs were tired of taking crowbars to the shins, believing the Nationals were violating unwritten rules by having the audacity to steal bases and swing at 3-0 pitches when leading by five runs.
