TOR: They get Allen, who although has less value then OG still has a good amount with value. They also get Okaro who was recently the 6th pick abd aklthough has been dissipointing offencivly could develope well. They get a favorable swap which could be valuable because the cavs are a win-now team without many frps.
CAVS: The Cavs get OG who would be the perfeect starter next to Mobley. Having OG would get them more spacing for Garland and Mitchell so they could b e more effective. Boucher is a upgrade over Okaro because he's a better shooter.
