I think Edge is the biggest need. They simply do not generate enough pressure.
Corner is next. They don't have a true alpha corner on the roster. And they might not have a second guy either.
I'd like them to address RG by either keeping Dotson or finding a replacement but I don't think it's as big a priority as others. I'd be okay with a rookie or a cheaper guard than Dotson if he gets too pricey.
After that it's mostly a bunch of positions that I think can stand to be upgraded. Third receiver. ILB. Stuff I think we can manage.
