so swerve question from someone who has never done swerve. Would having a 2 inch or 3 inch wide wheel be more beneficial? Our team has done west coast drive with 3 inch wheels in the past. One thought is that it would be harder to turn, the other is that it would be better for defense.

This is correct(ish).

You get a traction gain, but at a maneuverability loss. It likely makes more sense to keep the maneuverability to play better positional defense rather than pushing.
