If Detroit offers us Bey and #5 that's an amazing deal but I think they see him as part of the core there with Cade. I can only see them doing that if Holmgren falls to 4. I'd still make that deal and take Mathurin at #5, thus filling two wing positions at once but I have a feeling most Kings fans would rather just take Chet at #4.
I get why a lot of people don't think Keegan Murray has enough upside to take at #4. When you watch Ivey or Banchero they've got elite athletic ability even at the NBA level. When you watch Murray he's often finishing through contact against smaller defenders because he lacks the burst to get over or around them. It's hard to argue against his production though -- scoring ugly is still scoring. But I at least see the reason for concern. The thing that confuses me about the conversation around Keegan is why everyone keeps labeling him as a bigman. Offensively he's a wing -- his offense is generated either slashing to the basket off the dribble, spotting up on the perimeter, or with the type of mid-post moves typical of taller NBA wing players like Rudy Gay, Harrison Barnes, Paul George, Kawhi Leonard. Defensively he's also a wing. His blocked shots usually come off the ball when rotating from the weakside. He matched up fine with ball handlers on the perimeter. I don't think he's going to be guarding a lot of PGs one-on-one but checking them for a few seconds until another defender rotates over, sure. Is it simply because he's not an elite athlete that he gets the undersized bigman label?
In any case, I wouldn't be that worried about his fit with Harrison Barnes who is a free agent at the end of next season and with money available for a max free agent, it's quite possible Monte will explore other options before committing to bringing Harrison back on another contract. The core right now is Fox, Sabonis, and Mitchell with other Monte acquisitions like Donte DiVincenco, Terance Davis, Chimezie Metu, and Damian Jones likely to continue their supporting roles for a few more seasons. If we draft Keegan he becomes the only Monte guy currently in the rotation who can handle the SF position for anything more than spot minutes. That is unquestionably our biggest need.
