This builds off a trade suggested by Zach Lowe on his Lowe Post podcast (he suggested LaVine for Westbrook and both FRPs with protection on one of them). This expands this to get Bulls a 3rd FRP for Caruso.

Lakers get more size with Toppin while taking Fournier. Lakers would get 4 SRPs for Fournier but give two back to get Toppin (who provides size as a 4 and undersized 5) and has catch and shoot 3pt% comparable to OG Anunoby (not less volume and minutes). Given that Toppin is positionally blocked by Randle, it is unlikely that NYK would look to extend or re-sign Toppin after his rookie deal. For the Lakers, this means they opt out of cap space this summer (they get their pickup in LaVine), add 3 players who are presumably good catch-and-shoot 3pt shooters, and get a couple of SRPs to replenish their draft/trade capital. Plus, Toppin is already under contract for next year.

Bulls ship out LaVine for 2 FRPs, take another for Caruso (while taking on Westbrook as an expiring) as they currently sit in 10th place in the east and don't appear to be a contender with this group.
