You have to be careful about the upward trajectory projection with guys who are splitting snaps. The NFL is littered with players that have out lying season statistics, particularly RBs and TDs. Probably the best recent example is Aaron Jones who parlayed a superbly productive season into a $12mil/yr contract with GB and never duplicated the scoring production. That said, I’d be happy if Beane got Cook signed for that same contract, but I’m not so sure it’d be the best idea if it was inflated to $15mil/yr.
