There's more to it. Lineup construction goes deeper than any of us fans realize. How opponents would try to navigate a lineup, who might see more fastballs because of who bats in front or behind him, how you might play certain situations (i.E. - not having two base cloggers speed-wise back-to-back, etc.). OBP guys around RBI guys. in the case of a guy like Devin, he leads the team in HBP and has double digit walks. Those are all RBI opportunities for the guys behind him (Lopez, Nicholson, Daly) even if he's not seeing a high average right now.
