I am just waking up and don’t have the exact numbers but Knox had an abysmal catch rate his rookie season and made a big jump from that sophomore year (not a high bar to clear, though.) He did even better after that and got paid what appears to be a laughable contract, even before Kincaid was drafted.
edit: drops are notoriously not tracked well but fox sports has him at this, worse than his rookie season:
