For the Celtics, I say "meh," but I guess if you have to do it it's a fine alternative. I mean, that's the thing, the C's standard home and aways are some of the best uniforms in all of US sports, so any alternate uniform is going to be a down grade.
Of these "City" ones, I really like:
- Pacers
- Bucks (ignoring patches)
Very intrigued by seeing Sacramento in action.
The Brooklyn and DC ones are pretty good as well.
