Stop being a bunch of chicken littles. We may very well lose Lovett, that sucks, but Burden ain't leaving, heard nothing that says Cooper is leaving, Mekhi Miller is a stud, and according to some sites (numbers) Wayne was a higher rated recruit who has been playing defense because of lack of room at the WR room.
Let's assume we have Burden, Cooper, Miller and Wayne next year. Is that any worse than what we have right now? Assuming Burden and Miller take the big steps forward that Lovett made last year, that's really a better corps than we currently have. Would Lovett make it better? Sure, but the sky is not falling anymore than it has any other year. Did it suck when Wingo transferred? Yup. How was our D without him? Pretty fancy I'd say.
TL/DR....calm your nutty selves down, let it all play out. If we are 5-7/6-6 next year, feel free to go nuts, until we see how that plays out too....
