If every one of those guys is on the board when I'm picking at 17, I go with Klay Thompson. He's got good size for a SG, and fills a big need for NY as a sharpshooter. This team could really use a full-time sharpshooter to spread the floor, and you know exactly what you're getting.
Chris Singleton would be my second choice. The only hesitation is that Klay is that damn good and fits the need so well.
Brooks might end up being a better scorer than Klay, but I have have fewer question marks with Klay. Brooks might have trouble adjusting to being off the ball more. Brooks can create his own shot well, but how well would he spread the floor for our star forwards? I'd be very happy with Marshon Brooks, but I just prefer Klay.
Jimmer...I see him possibly being the next Stephen Curry. Might be worth drafting just for that, or even for trade value. I wouldn't really mind if NY got him, but I don't like his size, nor his defense.
Biyombo is too much of a gamble, IMO. He could be the next Ibaka, or he could be complete garbage. And the odds are he'll be closer to the latter than the former.
Faried is kinda small, IMO. Definitely a 4, not a 5. Could be good and useful, but would be a limited contributor behind Amare.
Markief would be nice if he's the best guy on the board, but I'd rank him #6 on your eight man list. And Montiejunas would be #8.
