Pat Mah. is expected to throw for around 300 yards. Based on his talent level and lack of a real ground game this is a reasonable number. Of the 300 Kelce probably good for 70 of those. That leaves 230 for the rest. JuJu while not a number 1 receiver in talent is clearly the number 1 receiver on K.C.  Mahomes is expected to throw close to 40 times. Not unreasonable to expect JuJu to have 6 or 7 targets. 

 JuJu over 50 yards receiving plus 175.
