A first couple those linked to teams that actually had terrible IS numbers in the boxscore, 9's and 10's so they haven't invested in IS at all. The next 2 linked to teams that put up 12's. In in every example you won a ugly, low scoring game as a result.
None of those numbers are teams that have invested heavily in IS my friend. 13's are a minimum but the top teams are putting up 14's and 15's. Like these 2 teams:
(58832733)(58832734)Of course everyone has different theories on what works best.
