You aren’t missing much. People taking him in the 3rd are insane in my opinion.
Since 2011, Carolina has thrown the fewest passes in the league to RBs. https://twitter.com/ScottBarrettDFB/status/858938737400696832
That could change, but then McC drafters are betting that a redesigned offense with middling WRs can find success while relying on a rookie RB. I’ll pass.
Other side of the coin is that Cam needs a reliable pass catcher, Cam is excellent in mid-rang passing efficiency, and McC was named the best route runner in the rookie class.
He could be great, but I won’t be risking even my 4th pick in my dynasty’s rookie draft. I see too many options with higher ceilings. In a normal league, you need guaranteed production in the 3rd round. 0% chance I even consider McC.
