Talib instantly becomes the most talented, and most troubled, cornerback on the Patriots' roster. Lombardi believes the Patriots will line Talib over the opponent's No. 2 receiver and double-team the No. 1. That has been the Patriots' tendency with their No. 1 cornerback.
McCourty has some experience at safety from the end of 2011 and played the position last week.
The move to acquire Talib plainly shows the Patriots are all-in for a Super Bowl this season.
