Pakua has had significantly more targets and has been outstanding after the catch so his drops are insignificant.
Kupp had an off day and I don't think is fully recovered from his injury.
Tutu has improved and hopefully will continue to improve.
Higbee has always had a drop issue and McVay doesn't use the tight ends enough so when he does it is usually a costly mistake.
McVay's passing game is limited, actually his offensive schemes are limited and offensive. He burns too many timeouts and relies one receiver too much
