Chargers TE Kory Sperry is unlikely to make the Chargers' 53-man roster. Sperry was originally non-tendered this offseason, but was later signed to a one-year deal. With four superior receiving tight ends on the roster, however, Sperry is the likely odd man out. San Diego will go forward with Antonio Gates, Randy McMichael, Dante Rosario, and rookie Ladarius Green.
