The Pollard Connection[edit]
Beginning in 2008, while Pollard was with the Kansas City Chiefs, a series of events began to take place that would alter the course of four Patriots' seasons.
In 2008, Pollard got knocked down to the ground while trying to sack Tom Brady. On the ground, Pollard lunged at Brady’s legs, connecting his red Chiefs helmet to Brady’s left knee and tearing the quarterback’s anterior cruciate and medial collateral ligaments. Brady’s season was prematurely over.

In 2009, while Pollard was with the Houston Texans, Brady threw a pass to
Wes Welker to the short left side of the field, which he then took up the field. Pollard closed in on Welker fast, forcing the diminutive receiver to cut to his right, possibly faster than he anticipated. His left plant foot slipped and he tore his ACL and MCL, missing the playoffs that year.

In the 2011-2012 AFC Championship, Patriots tight end
Rob Gronkowski caught a pass of about 20 yards with Pollard in coverage. Pollard wrapped Gronkowski up to take him to the ground. As Gronkowski hit the turf, Pollard’s right thigh forcefully landed on Gronkowski’s left ankle. Gronkowski suffered a high ankle sprain. Gronkowski played in the Super Bowl two weeks later, but the injury helped limit him to just two catches for 26 yards.

In the 2012-2013 AFC Championship, Pollard made a helmet-to-helmet collision with
Stevan Ridley that forced a fumble and the Ravens recovered it. Ridley eventually left the game due to a concussion and the eventual Super Bowl champ Ravens won the game 28-13.
