The Lions have extended the contract of quarterback Shaun Hill for one year. That means that he is under contract with the Lions through the end of the 2011 season. Originally he was set to become a free agent after this coming season, but the Lions obviously want to keep him around as Matthew Stafford's backup for at least two seasons.
Hill was traded from San Francisco to Detroit earlier in the offseason for the sole purpose of being Stafford's backup. We all saw what a debacle Daunte Culpepper was last year as Stafford's backup, so one of the top priorities this offseason was to find a player who could come in and play well if an injury were to happen to Stafford. Hill fit the bill for that role, as the Lions were able to trade for him for only a future seventh-round pick.
With Hill locked up for two more seasons and Stafford locked up for many years to come, Drew Stanton is the only quarterback on the roster set to become a free agent after next season. Whether or not he will be brought back is dependent on what happens during the next season, but the same can't be said for Hill and Stafford, as both of them will be on the team through 2011.
