STL was not bad for many years, that is extremely incorrect.
Unless you are citing them being bad in 2007, 12 freaking years ago.
They made the most of their mid to late 1st round picks, which they had because they didnt trade all of them. They made some good trades and even some bold ones, such as Schenn and ROR, respectively. They struck gold with their goaltender halfway through a very muddy season in which they fired their coach.
Lets not act like they stripped it down and went through some serious rebuild, which is why tanking is absolutely not mandatory to building a champion.
