The craziest wave of free agency is in the books, as most teams have completed their strongest open-market push to position themselves for the 2013 season. The Patriots have spent the majority of their cap space, most notably by retaining cornerbacks Aqib Talib and Kyle Arrington, and adding wide receiver Danny Amendola and safety Adrian Wilson. The Pats entered free agency with $25 million in cap room, and it’s hard to perfectly quantify how much they’ve got remaining because not all contracts have been filed with the NFLPA just yet. An educated guess here is that they have $9 million left to spend. Keep in mind they’ll need to save $4-5 million for draft picks, so the heavy work is done. With that in mind, the Pats have addressed some needs but have some areas that still need to be addressed. What’s done: L  Shored up secondary: The Patriots liked their secondary’s progress after the Talib trade, and they’ve decided to give that group another run. Talib will man the left side with Alfonzo Dennard at right corner if he is available, and Arrington will slide into the slot. This also ensures Devin McCourty will remain at safety, and he could have a new right-hand man with Wilson joining the mix. Wilson is a strong leader and an intimidating presence who will improve the middle of the field. The Patriots have done their best work in free agency in this area.
