Nick Chubb is a sell high guy IMO. He murdered one of the worst,if not the worst, defense in the league. He's trying to sell high. I'd much rather have Cooks as his value increased alot now that Kupp is out for the year. White is about to be TD vultured by a healthy Sony, returning Burkhead and now i wouldn't doubt BB keeps mixing in Patterson.
TL:DR- Nix this trade, hold on to Gronk/Cooks.
