For years opposing offenses were able to circle the Patriots on their schedule and know that they could log big numbers against the secondary. That’s no longer true, and New England has Talib to thank for that. His standing as a shutdown cornerback is no longer up for debate. First he took down Tampa Bay’s Vincent Jackson, then Atlanta’s Julio Jones, and finally Cincinnati’s A.J. Green. All three were impressive feats, but the way he erased Jimmy Graham from Sunday’s 30-27 win may be his most impressive performance to date.
