Trade Kupp for a boatload while he's on fire?

Got the Kupp Stafford stack going right now. 8 man PPR league my wrs are diggs kupp cooks, rbs are zeke kamara najee aaron jones. I could potentially get mccaffery + maybe more based on interest. Should I ride the wave with Kupp or trade him for a ton. Btw I am probably one of the top teams in the league if that changes anything

You’re pretty stacked at RB already in PPR. Kupp could finish a top 5 WR this season with Stafford throwing to him but historically the wide outs that pop off in the first few weeks usually don’t sustain the pace. If you can package one of your RBs with Kupp and get a good RB/WR return I would do it. At the very least go fishing and see what you can catch but aim high.
