It's a little more complicated than that TXRams. Fisher or Snisher have been absolute wizards in drafting and signing defensive players. They've had some whiffs here and there, but they've found absolute gems in piles of charcoal on the defensive side of the ball. Offensively, they finally addressed the Oline in a big way last year and Wichmann, Havenstein, and Brown look to be above average at least.
Where Fisher has failed, and where historically he has always failed is drafting WR and overall offensive philosophy.
I won't deny that Snisher have a knack for finding and developing defensive talent. I'll even give them a pass on the whiffs and there have been a handful of them. But definitely more good than bad.
But, where Fisher (and I blame Fisher because Snead can only draft, he isn't a coach) has failed is developing the offensive side of the ball. Yes, he finally addressed the offensive line which I give him credit for. He still can't find a WR because he doesn't give any of them a damn chance to prove themselves! We had a ton of receivers in camp and from then until now, I don't see any of them having a clear advantage over the other (short of Nelson Spruce, he can actually catch). How is he going to find the next Isaac Bruce if he doesn't give his WR's enough reps during preseason? It's not hard to see what you have at running back, give the receivers more chances.
Whether fair or not, a coach is judged on the wins and losses and Fisher has lost more than he's won in his tenure with the Rams. If he was a first round QB, he'd be labeled a bust based on those numbers. Why can't a coach be judged the same way? He's been very stubborn in sticking with his philosophy even though it's been proven to be a losing one. Smart people know and accept their weaknesses, he does not. He instead continues to think he's the smartest person in the room and either hires offensive idiots (like Schotty) or handicaps proven offensive minds (like Groh).
When I put all of it together, he's a bust...that's my humble opinion and my criteria may be unfair. But...there is no denying that he hasn't even been able to coach all this talent into a playoff contender.
