No. 3: Pascal Siakam, Toronto Raptors
The Toronto Raptors have a lot of similary-shaped pieces with which to try and construct their roster moving forward. It's sort of like trying to assemble a salad with only various kinds of ruffage; at some point, you wish you had a few hard-boiled eggs.
That roster crunch will almost certainly lead to changes this summer for a Raptors team that missed the playoffs entirely this season. Pascal Siakam, as the oldest member of their forward core with the shakiest perimeter shot, could be the one sent out as the team builds around a frontcourt of Jakob Poeltl, Scottie Barnes and OG Anunoby.
If so, the Spurs should at least pick up the phone and inquire about the Cameroonian forward. He and Wembanyama could share the two big positions and switch most matchups, with Wembanyama's shooting opening space for Siakam to dominate inside.
Siakam speaks French fluently and could be an excellent veteran mentor to Victor. At age 29 he is still in his prime, and he is very used to playing beside other ball-dominant stars. Siakam is an underrated passer as well, and will set up his rookie teammate to succeed. If the Raptors are selling, the Spurs should look into it.
