NFL street. It was a sport game, but fun. What other sport game let you run on walls, draft players, do backflips, style catch, and dance like a mad dog while playing some of the best tracks ever in a game?

For baseball, EA Sport's MVP Baseball 2005. Not only was the game's controls easy to pick up (2K Sports is a huge offender in this category) but there was the sabermetric aspect to the game as well, who do you play in terms of numbers, etc. That and the fact that Manager and Owner mode was hugely deep to the point where it nearly played like an RPG. That's right, a sports game as an RPG. That's pretty awesome.
