Thanks!
Make a swerve drive setup.

In all seriousness though the real issues with the mecanum wheels in terms of pushing are this:
-They aren't 100% effective at transferring power, a lot of it is lost. This forces you to have to gear higher to be able to go at a reasonable speed which makes you less capable of pushing. It is difficult to do a shifting gearbox with mecanum wheels because each wheel has it's own gearbox and shifting gearboxes are quite heavy.
-They are easily pushed sideways. They are designed to do this so that you can strafe, but most of the time when pushing is done it is not done front of pushing bot to front of bot being pushed but front of pushing bot to side of bot being pushed.

Hope this helps. As a team that used mecanum wheels last year I would advise against them because when the eliminations roll around and you are facing defense, being able to be pushed sideways easily really hurts your chances and it makes winning very difficult.
