3. Bobby Portis, Milwaukee Bucks
Looking at strictly size and outside shooting, it doesn't get much better than Bobby Portis. The 27-year-old has been shooting at a 40% clip since the 2018-19 season and knocked down a staggering 47.1% of his threes in the 2020-21 season.
Every contending team needs someone like Portis on their squad -- a guy who plays hard, stays within his role perfectly, and buries jumpers at a deadly rate. His seventh year in the league was by far his best, as he put up 14.6 points and 9.1 boards for the Bucks as they look to repeat as NBA champions.
Portis has a player option and, by all accounts, loves his situation in Milwaukee. Since he's on a perennial contender playing with Giannis Antetokounmpo, it's hard to blame him.
Strangely enough, I feel like maybe a second championship could actually work in favor of Portis looking to get paid and branch out more so than being knocked out with unfinished business. That's just my own thought process though, and we won't really know more about what's going on in his head until the Bucks' season comes to an end.
While the Spurs have decent shooting options in their frontcourt right now, Portis would be a substantial upgrade and put them closer to where they need to be as a glue piece. If he's fielding calls this summer, they should give him a ring.
