Credit u/tayzgaming123 for the initial ideal, I just found a way for my knicks to get involved and get off Fournier's contract while getting back some familiar faces. Their involvement helps the Pistons cause they only care about the pick. Here they get back multiple seconds they traded along with the rights for their 23 pick. This only works if they have a bigger deal in mind (John Collins?) and want to trade it elsewhere otherwise we're not needed. The Reddish/Diallo swap is just 2 teams trading each others trash and hoping they can reclaim the value
