Not sure if I agree. Again, I am using experience from what I have seen. My brother in law completely tore his right pec & waited months before actually getting treated. He's back to bench pressing like normal as well as competitive fighting.
If you got it treated right away and don't prolong the surgery, you'll be fine. It will just take time.
Need I remind you Adrian Peterson tore an ACL then came back to rush for 2,000+ yards ; ]
