There's nothing *bad* about Alonso's BB or K rates, if anything the K rate is a positive for a player of his power. But what I'm getting at is that even with all those extra balls in play he's not hitting for average and he's not going to be an OBP stud as a result given the lack of elite walk rate. So while I agree that Alonso is a better hitter than Schwarber, when talking about the risk/reward of extending him he has more in common with Schwarber than he does with Murphy or Olson, who are diversifying their value to a greater degree than Alonso's (oversimplified) approach of 'hit fly balls and enough of them carry over the fence' without defense, baserunning, or out-avoidance as a plus.
