Put another way, if the ball is a mere 6" off target, you'd rather have the ball bounce off you (and then have to go chase it) than see a robot with the ability to take a half step to the right?

Based on initial ball launching prototypes, yes I would.
My point is that the ball will never be anywhere close to 6" from being caught, it will be much farther away and completely un-catchable because a mecanum robot can not hold field position. If your catching robot uses mecanum wheels, pushing it out of the way will be a common and effective defensive strategy. In a game like this where field position is everything, a mecanum robot is at an extreme disadvantage.
The only role I can see a mecanum robot playing effectively is a robot that cycles the ball by itself with no assists. As soon as it tries to play a role where it has to stop and wait for its alliance to do something it would lose its field position and ability to add assist points.
