Statistical analysis can only be so relevant as to bring a general blueprint as to a players skill I think.
Cases in point
A fantastic wide reciever - Think Rookie to Fresh Randy Moss. If he draws double coverage at almost all times then that accounts for the bulk of his impact. He might not be making a catch, but he is taking one player out of the game in a certain way - basically removing a defensive advantage.
Nmandi - If a ball is seldom thrown at you - it will be difficult to get the highest INT total, so that's the stat column shot down - BUT - his stellar play removes offensive options because the Raiders know that the ball will seldom see his flank.
Clay Matthews has the "Gameplan for him" factor in abundance, and you could see in the latter part of the season that he was drawing more blockers, all the while not playing at peak health.
Raji and Jenkins have had stellar years, I doubt they'd have been as impactful had Clay Matthews not been a part of our team.
Some players are impactful by their sheer numbers, others are impactful in how they open up opportunities for other players, some can do both.
Matthews can do both.
No green and gold goggles.
