you can't judge any GM on their hits and misses imo. ultimately it comes down to the player.
but what you can judge Danny on is his ability to put us into position to improve. he got an A+ leading up to '07/'08. and I give him an A+ for what he's done for 2016, that off season is going to be huge with the salary cap situation increasing, our picks plus the Nets(which could potentially be top 10 picks). the future is very bright and there's nothing more you could ask for from a GM.
