San Diego Chargers running back LaDainian Tomlinson is worried that his window for winning a Super Bowl may be closing.

Tomlinson says that explains his actions in two games over each of the past two seasons.

Tomlinson, normally a very quiet player, was outraged in 2007 when the Patriots demonstrated what he considered to be no class in the final moments of their win.

Last year, Tomlinson had words with quarterback Philip Rivers and then moved away from him on the bench during an eventual comeback win over the Tennessee Titans.
