Why don't the San Diego Chargers get rid of Nate Kaeding? They should get rid of him instead of L.T.?

As everyone knows, LaDainian Tomlinson was released by the San Diego Chargers today, I think thats a mistake, he still has a few good years left in him, the Chargers need better run blockers. Seriously, in order for the Chargers to be better they need to get rid of Nate Kaeding, just like Marlon McCree was released by the Chargers, and Drayton Florence, for their bone-headed mistakes they made in a playoff loss agains the Patriots 3 years ago.
