John Collins is an Instant Upgrade
For the Spurs, they would get a major front-court upgrade at power forward in Collins while also consolidating their assets. And while White is certainly a good player, he’s the oldest of the team’s recent draft picks and may not fit their timeline. Plus, the Spurs already have Devin Vassell ready to replace him, as well as Joshua Primo waiting in the wings.
Acquiring Collins would add some much-needed scoring punch to the starting lineup and help to alleviate the pressure for Murray to both score and create. It would also allow Keldon Johnson to slide over and play his natural position of small forward, hopefully benifiting him in the longrun.
With Murray, Vassell, Johnson, Collins, and Poeltl as the new starting five, the Spurs would have a great mix of offense with Murray, Collins, and Johnson carrying the load. While on defense, Collins' defensive shortcomings would be minimized by the other starters, thereby maximizing his overall value.
A trade for Collins would also reset the Spurs' bench unit. With White and Walker both gone, and Vassell starting, San Antonio would likely play Tre Jones, Primo, Doug McDermott, Keita-Bates-Diop, and Jock Landale together.
That would be a downgrade over the current bench, but San Antonio would still have around $30 million in cap space this summer. Additionally, by holding on to their pick in this year's draft, the Spurs could still end up drafting in the lottery. Using both would allow them to continue to improve the roster following a Collins trade and hopefully help them get back into title contention much sooner.
