Disagree. I would say LaFleur is better but remains to be seen on Campbell and KOC. Lions are one year ahead in their rebuild and due to various trades had 5 first round picks that have played 1 year while Poles and Flus have had 1 (Wright). He also has a veteran QB not a rookie. Campbell's 4th down decisions probably cost the Lions a SB appearence.
As for KOC, this year looks promising but he inherited had Cousins, Jefferson, and Hunter which gave him a significant advantage talent wise. LaFleur has a long enough track record and manged the transition from Rodgers to Love well enough for me to give him the clear nod.
So again I prefer to see how the rest of this year unfolds.
