I think the only player that a non workout could hurt is Exum, and that's just because there are questions about PnR that his tape doesn't fully answer. W/ Jazz wanting to run upwards of 65+ sets of PnR a night, he'd be responsible for a lot of that. I think you have to answer that question after hiring Quin Snyder.
I want Gordon at 5, even a little more than I want Exum. If we could solidly answer his position question and put him at PG, then he's an elite talent/ prospect, and I probably take him. But, if he is a 2 w/ a struggling jumper, then he is still a good player, but I am hesitant because I have both Burks & Hayward who are good 2's who can handle the ball, create for others, but have struggling jumpers. Burks & Exum have identical measurements, w/ Burks being heavier.
The workout doesn't show much, but it can tip the scale. They aren't held for no reason.
Now if anyone from the top 3 were to somehow be available, you take them in a heartbeat.
