Lions release pass rusher James Houston, who had 8 sacks as a rookie [Update: Browns claimed James Houston off waivers]
He doesn't play at the same speed after he broke his leg. He's lost the explosiveness that helped him succeed his rookie year. He's also not very disciplined and losses outside contain too frequently.
IDK that he's an upgrade over what we have, but I also don't think he will clear waivers.
