I'd try to get him back on a one year deal, nothing more. We need someone to fill in for Gregory while he's suspended and we need 3 good edge rushers. If Gregory can get his act together and proves to actually be a good NFL DE when he returns, then cut Hardy loose and roll with your two young stud DEs next year. If Gregory can't and doesn't, then find an edge rusher in next year's draft. The only real stud DEs in this draft both have a history of drug offenses. Spence got kicked out of school for his issues and Bosa had to force himself to live like a hermit after getting suspended for his. And these are the guys you want to replace Gregory with?
