I can tell a couple of things from this pic.... There is not a lot of atrophy..and not a whole lot of scar tissue build up around the scar.....
but it's obvious he's got a lot of work ahead of him as far as building up the strength in his lower legs....
but just from what I can see and what I've seen in other people this far removed from that surgery....he's either at...or close to being at the point where he can start to go hard building up his legs....he shouldn't rush back though...but I think being in the starting line up for the opening game is more than just wishful thinking
