This is by far the best fantasy basketball site I've ever been to. It took me weeks to find a good one. When I found pennantchase, I was hooked immediately. I would definitely recommend this site to any basketball lover.
I know it must take a whole lot of time to put this together and keep it updated. Really is awesome and the fact that it is free is beyond comprehension. Thanks for making one soul happy for a few minutes each day!
I first joined PennantChase during the delayed 2020 season, as I figured it would be a good holdover for fantasy sports. It has far exceeded any expectations I had. It has been great fun to take part in custom leagues, and I even joined one with three of my friends that I recommended Pennant Chase to. Great job making this site so accessible and the leagues so customizable.
I want to convey how absolutely blown away I am by the amount of detail you have put into this. As a former player, now coach, and forever fan of the game, I have played every basketball sim I could get my hands on over the years. Never have I found one with as much attention to detail, depth, and strategy as this. Now my biggest concern is keeping myself from forming a new addiction! The waves set up is perfectly flawless. The usage of all real stat factors and the ability to assign shot shares amongst players on the floor is something I have never seen in a basketball sim. This game is a masterpiece.
