Harrison Barnes dealing with the highs and lows of being the Mavericks' new go-to guy Posted Nov 27, 2017 If ever someone received a clear picture of what it's like to be the new go-to guy, Harrison Barnes got it this week. Heartbreak on Monday. Elation on Wednesday. This is the way it goes for somebody who now clearly is the Mavericks' No. 1 option when they need a basket. He'll no doubt get plenty of guidance from the player formerly known as the go-to guy, Dirk Nowitzki. (Dallas Morning News)
