Burroughs. I basically got effed over hardcore here, but I still think I have a top 4 team even with my #1 guy going down.
He is likely done for the season but if he is done he will likely get a medshirt and be back next year as the #1 or #2 overall pick. So for those who dont have a great keeper option this would be a really good pickup for next year.
There is also always the outside chance that he pulls a Tyrell Todd and shows up in January or February with a giant Brace on his Knee.
I'm not going to ask a lot for him... basically any decent backup would be acceptable.
