I disagree. Mecanums can be easilly pushed around, which will be very detrimental this year. They will be very poor at defense, as well as slow(er) than other types of wheel base. Speed will be extremly important this year, unless you have someone ferrying you pieces. A good 6 wheel, 8 wheel, or treaded robot will have lots of fun pushing around the mecanums, away from their lanes, and away from their poles, as well as delaying them in the middle.
