Fine for an inexperienced guy in his third year, give him a pass all you want, still doesn't make him good. Same goes for JP, he has shown some progress, but he really does suck and is probably the worst starter in the league right now.
And last year Spikes had 5 Int's, 3 sacks, 2 TD's 11 passes defended, more tackles, etc....
The production is a huge dropoff. I don't expect him to be Spikes, but he is making too many tackles from the side and catching players, rather then hitting them head on. That mean he is having troubles getting off blocks or he is out of position.
