While I admit these numbers to be way out of whack, mainly because of the special teams tackles...
The Philly SS position Considine and Lewis shared ended up with... 134 total tackles, 5 sacks, 3 Ints and 14 pass deflections.
Looking at the last eight games and extrapolating Considines numbers to sixteen... 102 tackles (68/34), 3sacks, 2int. 6pds.
Which had it worked out like that, would have been the #13 DB in a balanced scoring method. [.5 per T/A, 3pt per S/I].
His statistical outlook is good, but he isn't considered a big talent, which holds back his rankings currently.
