You guys need a coach! Sounds like a hockey match was going to break out!

Don't get discouraged just yet. Your team is new. You'll develop a race rapport in time. You guys still did really well! Once you iron out the kinks, you're going to get even better.

It sounds like the team plan didn't use everyone as well as it could have. Rather than have the 2 strongest guys do all the pulling, wouldn't it have made more sense to let everyone do some work up front? You felt like you got a free ride. You shouldn't feel like that after a race! You had more to give.
