Awesome site with lots of options. There are single-season leagues, keeper leagues, or my favorite – custom leagues. These typically have a salary cap and you run your team season to season. All 162 games are simmed, and some leagues will finish an entire season in just a couple of months. Then you resign your players, they all get better or worse in the offseason, and then you’re off to the next season. Extremely fun and addicting game!
