Nope, directed at the right place.
He's probably hoping for a bit more consistency. Check out Green's game log. There are plenty of games there in the single digits. Plenty below 5 points even. Hoping for more consistency isn't asking for LeBron James.
And while I don't share the Faried criticism, Jeff Green is 235 lbs. Asking him to box out someone 15 pounds heavier once isn't all that unreasonable.
He isn't asking for LeBron. Once again, overreact much?
Green was listed at 235 lbs before the surgery. There's no telling what he weighs right now (but he did report losing weight after the surgery, and expected this to help him play the SF spot better). Did he look like he had the same bulk as Farried (who is listed at 230 lbs, by the way). There's a reason why the team only considers Green a situational PF.
As for consistency: I advise you to find the most recent article on Jeff Green, where it's explained how recovery from his surgery can take as much as two years, and part of the recovery issues include occasional bouts of fatigue/exhaustion.
Also, if the OP really is concerned about consistency, then he should be singing Green praises for more than a month now. But somehow I don't think this is the issue here.
