http://www.indystar.com/story/sport...2-patriots-footballs-under-inflated/22089889/ Sources told ESPN late Tuesday that 11 of 12 footballs used by the New England Patriots against the Indianapolis Colts last weekend were under-inflated by 2 pounds of air (psi). The Patriots defeated the Colts 45-7 Sunday night to earn a spot in the Super Bowl against the Seattle Seahawks. NFL officials didn't comment. A source said the league was "disappointed ... angry ... distraught" over the under-inflated balls. Part of the investigation that still needs further vetting is how the 11 footballs became under-inflated. The balls are required be inflated between 12.5 and 13.5 pounds per square inch and weigh between 14 and 15 ounces. An under-inflated ball would be easier for a quarterback to grip in inclement weather, and there was heavy rain and wind in the second half. However, the Patriots' LeGarrette Blount rushed for three touchdowns against the Colts.
