WHAT? So you think it's possible to ever rise up to what teams like the Dodgers, Yankees, Mets, Padres, etc can assemble when those teams can buy the best on the market? What the Brewers have right now is absolutely on par with the best one can ever expect them to assemble. The only way for the Brewers is developing them in your system and acquiring via trade before they break out. Developing Burnes, Woodruff, Williams, Ashby and trading for Hader, Peralta, and Lauer is no easy to match order. So many things had to break right to get to this point. Avoiding injuries, improving spin rate, honing control, developing new pitches that work, and quite simply having all those pieces converge at the same time is an endeavor with really long odds. Injuries alone can derail the best laid plans. The Brewers have no room for error and can't simply BUY another 1, 2, or even 3 starter whenever things go wrong.
There is something very rare and special for the small market BREWERS when they're able to have a sustained run of years with pitching like this.
