Yes, he's a free agent. Last I hear he said he's be ready for spring work in April. So he looks to be just fine for the season.
Hmph! I even posted this link before and I really can't even remember passing over his name, much less considering it.

My guess is that I didn't think much of his size when I was looking at the list. I was looking for a beast-type WR for the Rams to pursue and 6'0", 198 lbs isn't anything to get dazzled by.
But he was pretty highly touted out of college(Missouri) even though he dropped further than expected(19). But while I'm not terribly concerned about Bradford and his ACL recovery, I'm less confident about a WR coming back quickly. It seems that even though guys can get healthy enough in 1 year to get back on the field, skill guys seem to take a year of playing in addition to their 8-9 months of recovery to get back to where they were.
True, there have been some freakish examples like All-Day but I'm uncomfortable counting on it from a guy the Rams are really going to depend on. The other Steve Smith leaps to mind even though I don't think his knees were in the same shape as Maclin's.
