SUPER BOWL or bust

I have Tillman,greenway, freeman, baron, burnett and just pick up brown-giants

Is brown a keeper going forward or should I keep Barron.

Is freeman a risk going forward or should I pick up wheeler/butler/urlacher going forward

Thanks Guru  

I would keep Barron. I would pick up Wheeler or Butler. Butler has higher upside, but Wheeler is safer, more consistent option.
