Patriots signed QB Mike Kafka and DE Marcus Benard to a reserve/future contracts. Kafka, 25, is a West Coast-style quarterback with a weak arm but smarts and solid accuracy. He'll head into the offseason hoping to secure the Patriots' No. 3 quarterback job, although New England often doesn't keep three signal callers on its 53-man roster. Benard led the Browns in sacks (7.5) in 2010, but has been a non-factor since. He can play both linebacker and end.
