1. Brandon Lloyd
Lloyd will be 32 years old in July, and his one year in New England was more hype than production (just four touchdowns). Even his reunion with Josh McDaniels couldn't salvage anything more than a one-year stay.
However, Lloyd has 70 or more catches in each of the last three seasons, and he's clearly the best pass-catcher remaining on the market. Eventually, a receiver-needy team is going to come calling with the right offer.
2. Steve Breaston
Breaston's inclusion on this list highlights how thin the remaining receiver class really is.
A nagging knee injury in 2012 kept Breaston from extending his streak of four straight seasons of 700 or more yards, and it's most likely the reason behind his continued unemployment status. He'll also be 30 in August, so there isn't going to be a rush to get him signed before camp.
However, Breaston is an experience slot receiver who has produced in the right situations. He now needs to find another one before the 2013 season.
3. Austin Collie
Collie is quite possibly the most interesting free-agent receiver.
A budding star as a slot receiver for the Indianapolis Colts, Collie saw his NFL career ravaged by a string of frightening concussions. Teams should rightfully be cautious about signing a player with the concussion history Collie possesses, but if healthy, he's likely the best combination of youth and talent in this shallow pool of receivers.
