how many managers does he get to blame before people look at his roster construction?
The roster and organization are regarded universally as amongst the very best in baseball the past five years. Why in heck would anyone point at him? Heck even the playoff failures, and current failure have zilch to do with Rizzo.
'12-Colossal choke job against Cards.
'14-Williams Clown Car Manager while Bochy owns him in a series where Williams had repeated opportunities to get things right and always made wrong choice.
'15-injuries and Williams stupidity have hurt us big time.
Rizzo owns everybody in trades, has one of the best collections of scouts/drafts in MLB, and has a team that blends veteran depth, with in prime guys, and youth, even has great pitchers in minors to fill holes at Zim, Fister and possibly Strass leave.
Rizzo is the last guy to blame.
Would think we wouldn't get spoiled so soon by his work as GM, but apparently so. Seriously, we've seen some horrific management decisions by prior Expos/Nationals GM's over the years and in general. Looking around the league the GM's who've done a better job drafting/developing/and making trades around the league can be counted with 1 or 2 fingers, if that.
What's gone wrong has to do with mental make up of certain players, and incompetent management, mixed with some injuries. The team is built so well they could continue to seriously contend, if they did absolutely nothing with FA's, for the next 3-4 years no problem. That's a well built team.
Don't mistake Williams being a block head, "Mongo" idiot, with Rizzo being a seriously flawed architect of organizations. Until Mcloughan arrived (and I detested his first, horrific draft), Rizzo was the only GM in town of actual quality, and luckily, he's not just quality, he's superb, I just wish he was a bit more trusting of the numbers, and a little less instinctive, and didn't have a soft spot for work hard/tough/blockhead morons like Williams).
