Yeah that was my first thought as well, it seemed really shallow.
He's a career 49% shooter. Yeah he can't shoot from deep, but he doesn't really do it much. His TO numbers are kionda high, but when you adjust for the fact that he has massive usage rates, I don't think they are too bad. I would definitely have Wade above most of the guys on your list.
Look at the 2010 Heat. This is their #2-8 rotation, in terms of min played. Michael Beasley, Udonis Haslem, Quentin Richardson, Jermaine O'Neal, Mario Chalmers, Carlos Arroyo, and Dorrell Wright. Wade dragged that team to 47 wins.
Frazier and Monroe I guess were combo guys, and were way before my time, but i don't think either are really 2 guards, no?
