1. DR has been an improvement over Chris Houston but he needs to be better if he wants to earn his salary

Why - The QB rating for QB throwing at him based on these numbers is 92.51which in my opinion is too high. Iunderstand that DR has had little help from the safeties but if my QB has a 92.51 rating I think he's having a goodday so naturally DR needs to improve. 

2. Grimes is better than Dunta at this point 

I expected higher INT and PD numbers since the safety is shaded towards BG, what surprised me though is that BG allows fewer big plays per target (DR=6.2%=5/81, BG=5.9%=7/119) which is basically what DR's main job is so I expected him to be better there.

Also, there isn't a big difference in the amount they are targeted (DR=9.5%=81/849, BG=12%=119/987)

3. Nickel, Dime and LB coverage is quite good except for passes defended. In fact, the interception rate is quite amazing. My only complaint would be that the big play% is probably a shade high considering a lot of the throws were underneath the zone coverage. Does this indicate missed tackles in the middle?? 

                        DR+BG                       Everyone else  

TD%               8/200 = 4%                15/360 = 4.2%

PD%              30/200=15%              5/360= 1.4%

INT%              6/200=3%                  16/360=4.4%                              

Big play%      12/200= 6%               26/360=7.2%
