He's the only real backup SF so that's an advantage on paper but 10th man minutes will probably shift around like they always do. Better or worse we know who the top 9 are going to be. LaVine and DeMar rotating at SG/SF and Keegan playing at SF is likely eating up those minutes for the most part. Going with the vets early is the smart call because this whole thing is based on ceiling. If they aren't in the mix of anything after a month or two and the Kings don't start thinking future first then this organization is doomed. Then there is no plan based on results and it's back to them trying to fight the waves carrying them out to sea. Just go with it because nobody actually drowns in this thing, it's a game. Going out to sea eventually brings teams into more stable waters so they can eventually swim back to shore.
The young guys aren't the worry, they're on rookie deals, they are older and more proven, they have time. This isn't too dissimilar to the situation Kevin Martin came into. He didn't just appear and get minutes, he slogged through his rookie year and it was incremental steps until the team started to have to tear down the remaining parts of the great Kings team because age/injury caught up to them and that opened up opportunity. This core is actually pretty close to the age of the Webber years Kings team. Everyone except Keegan is in that 30-36 range. There's only so much window there even if it does work.
