2. Jakob Poeltl
There isn't much to complain about when it comes to Jakob Poeltl's performance with the Spurs this season. He contests shots at a league-leading rate, blocks nearly two shots a game, and is on one of the best contracts in the NBA.
With that said, Poeltl was close to being dealt on trade deadline day if Charlotte had only agreed to throw in a 1st-round pick in their side of the trade. Even with how great he's been this season, there are some noticeable holes in Poeltl's game that might never improve.
It's hard to see Jakob developing any kind of jump shot at this point in his career, and that's becoming a skill more and more centers in the league are polishing. On top of that, for an interior player like him who will probably get to the free throw line more than most, his 46.6% mark from there can really be hurtful in close games.
Just like McDermott, Poeltl is doing well in his current role, but that doesn't mean it's completely safe going forward. If the Spurs are able to use their newfound assets to trade up for a premier big in the 2022 NBA Draft, his starting spot could be in serious jeopardy. The same could be true if they miraculously land a big name like Deandre Ayton in free agency.
The Spurs would be a perfectly fine team next season with some additions and Poeltl starting as their center, but being 'perfectly fine' might not be enough for this ambitious front office.
