Calculated risk more than anything - if there is a pitcher to take the training wheels off for - he's the right guy. Chance to go for the kill at home - and with a legitimately terrific safety net if it doesn't work. Got them a small edge against a more or less equal team. With the NLCS starting Friday, it STILL lets them use Greinke-Kershaw on full rest for Games 1 and 2, you just flip the order. It takes the chance to pitch Kershaw 3 times in the NLCS off the table, but I suspect that was never a real option.
