The Detroit Lions turned a lot of heads in 2011 with a 10-6 record (most wins since 1995) and made the postseason for this first time since 1999.
Even better news for Detroit Lions was their franchise quarterback Matthew Stafford remained healthy for the whole year, producing one of the best statistical seasons in NFL history with over 5,000 passing yards and 40 plus touchdowns.
Meanwhile, his partner in crime Calvin Johnson produced one of the best statistical seasons for a receiver in NFL history, with 1,600 receiving yards and 16 touchdowns.
