I think I have figured out why Shades had success early and continues to flounder the longer he remains a head coach: (As much as some of you will call it "redundant" doesn't make it any less true):
1.) Shades inherited a Super Bowl caliber team, complete with players, coaches and team culture. It's not an indictment. It's no crime. He, in fact, took over a SB-winning team including veteran leaders, so he didn't have to worry about that aspect of the team. He had a plethora of legit leaders on that team, including Harrison, Ward, Miller, Hartwig, Aaron Smith, Keisel, Farrior, Ryan Clark.
2.) And they had a legit Hall of Famer QB, even though they seemingly tried to ruin his talent, he rose above the anal tendencies of pee-your pants offensive schemes to "rise above" them and produce in the 2nd half to pull out wins. Franchise, HoF QBs don't grow on trees as we are seeing 1st-hand.
So, in the conditions he arrives at the Steelers, with All Pros and leaders all over the place, he was well suited to take that team over. But as the leaders and Pro Bowlers retired, he had nothing left to offer. On his own, without veteran leaders, his entire organization has grown sloppy and lazy, something a bevvy of players have spoke out on, even a rookie QB , mentioned practices that lacked discipline. How many times do we see the team LINE UP wrong causing a flag? LINE UP wrong? That is a team discipline problem and it's been happening with more regularity as this s--t show continues. They are getting WORSE.
And of course, shopping for assistant coaches at the Micky Mouse store doesn't help. When your assistant coaches are decided by how good of buddies they are, and how little they threaten your authority, you end up with a s---t organization, which is exactly what we have now. We have a garbage head coach, not knowing how to even "lead himself," never mind the entire team. Yea, sure, the media is all onboard with the Tomlin fraud show, but alas it is just bunko, regardless how how many times the media pretends Shades is a legit stellar head coach. He ain't.
