With as deep as we are there's no need to rush him back at all.
Does anyone know if it was just an ACL tear? I know guys like JK Dobbins who also tore their LCL, hamstring, and meniscus take a lot longer to recover. A full year and he wasn't back to himself.
Then there's freaks of nature like Adrian Peterson who tore his ACL/MCL and comes back in less than a year and breaks records rushing for over 2000 yards and wins a MVP.
I guess you just never know how each body will recover.
