I'd keep #1 and take Cade with no hesitation. Detroit will never attract free agents and finally have an opportunity to land a franchise talent. The fans around here are pining for him, and with his talent level and versatility, he looks to be a highly likely cornerstone.
What makes you so sure that he’s a franchise talent? He barely averaged 20ppg, had one game with 30+ pts. His 3pt and FT percentage was solid, but overall FG% isn’t great. Rebounds well enough, but reached double digit rebounds in a game just twice. Only 3.5 assists per game. He seems like a good prospect, but I don’t see why people are hyping him up like he’s Carmelo Anthony coming out of Syracuse after winning a national championship. Cunningham lost in what, the second round of the tournament? I don’t see a player that’s a lock to be an all star like we did with Carmelo and KD.
Carmelo only averaged 22.2 ppg at Syracuse. And I know Cuse won the title with Melo, but his 6 NCAA tournament games this was his scoring: 17, 13, 18, 20, 33, 20. Scoring in college is just a different animal to scoring in the pros.
As for Durant, he lost in the 2nd round as well. Durant was a better scorer at 25.8 ppg and a much better rebounder at 11.1 rpg, but KD only had 1.3 apg and 2.8 tpg. He showed almost no passing ability at all. And for as good a shooter as Durant has become, Cade is basically the exact same shooter in college that Durant was (KD 40.4% on 5.8 attempts, Cade 40.0% on 5.7 attempts - Cade better from the line, KD better from 2).
All that said, I also don't think you can put much stock in college numbers. Some of the best college players make terrible pros, while some very middling college players make excellent pros. They quite simply aren't super comparable.
