Obviously, Philly needs a Harden replacement, and with Nurse in Philly and FVV in free agency, this seems like a pretty natural fit.

On the Toronto side, Harden certainly changes the timeline, but he is also an offensive upgrade on FVV, and would have a plethora of PnR partners with the Raptors, while providing shooting. With OG, Siakam, Barnes and Poeltl he would also have lots of protection defensively.

It wouldn't have made much sense a day ago, but at this point, who says no?
