Rotoworld has taken the time to compile and rank "the most accurate free agent list on the internet." While you might take exception with their rankings (e.g., Mark Sanchez, Jake Locker, Josh McCown, Brian Hoyer, and Matt Moore are all valued higher than Ryan Mallett), it's a good reference to have handy when you're considering who the Houston Texans should target once free agency begins in a few weeks.
Speaking of players who were on the Houston Texans' 2014 roster, Rotoworld has Mallett as the No. 6 QB as noted above, Derek Newton the No. 4 OT, and Kareem Jackson as the No. 6 CB available.
