Yeah, I agree - was thinking they would go taller and a better 3p% like Coffey. End of bench guy, he'll work.
Here is another write-up on Waters that goes with what you stated -
Lindy Waters is known for his compe ive and disruptive defense, particularly as a wing player, with a reported 6-foot-10 wingspan. While not an "all-world" defender, he competes well and doesn't hurt his team on that end of the floor. He's been described as a solid defensive player with the agility of a guard and the length of a wing, getting into passing lanes and disrupting plays according to Golden State Of Mind. His defensive rating has varied slightly year-to-year, but he's known for his hustle and ability to make an impact on that end of the court
