Out of all the leagues I can think of my favorite is definitley the NHL cap, it's fair enough and allows teams to stay competitive however their market is doing plus it hasn't really changed much over the years. Teams trade and have plenty of ways around it too so nothing gets out of hand usually but you gotta find the right dance partners making it more interesting. Don't really have anything specific I'd change other than having a little larger contracts and lower minimums so more players can get a chance or make more dough like some or the other leagues. Speaking of other leagues the leagues who are allowed to spend extra money take all the fun out of it like the MLB and I've never understood it, the NBA is pretty close to the NHL but the difference between contracts is ridiculous when the talent is very close.
