We have had 17 years of patchwork- plugging holes with spare parts to make it work. That got us a lot of mediocre teams that were always close but not quite, gave us hope every year that they might just pull it off, but never did. Going back to 2006, we have had one 4 win season (2010), the rest are mostly 6 or 7 wins, sometimes 8 or 9.
