Marvie,
I still like the maroon ones, the alt teal ones look good, but do my a favor and just change that second color "teal" to a light carolina blue on both the maroon and teal ones like the concept pics. (To get light carolina blue your color palette needs to be set all the way over near where blue turns into purple and then all the way down and to the left.) You are still too close to green with the color in your pics. I wanna see which version looks better.
The yellow jersey is also interesting. I'm pretty sure you can find a jersey type that will allow you to make the sleeves color black from the glove up towards past the elbow to match what you did with the socks, that might look kind of cool.
Scrap the rest of the designs tho...
