Dwayne Bowe
Wide receiver Dwayne Bowe gave the Chiefs several decent seasons in the late 2000s and early 2010s, but his 2010 campaign was a clear outlier. He finished that year with 1,162 yards and a league-leading 15 receiving touchdowns, including 7 in a three-game stretch. For the season, Bowe actually scored on over 20 percent of his receptions, a pace which obviously was not sustainable. The following year he nearly matched his 2010 yardage total but only managed 5 touchdowns, and it was all downhill from there.
