Even if Talib's injury is what lost the game (it wasn't), the bigger problem then is a defensive system/coordinator completely reliant on an injury prone to be completely healthy. What lost the game is the same thing that lost the game last year, god awful drafting/talent development from Belichick over the years and a roster full of players who consistently fall off in the post season. Everyone on the entire roster sans Jamie Collins and maybe a few others had a below average or worse game. Brady, Mankins, Solder, Chandler Jones, McCourty, etc., all played noticeably worse than they did during the regular season.
