It's obvious that KO is learning and changing his approach, which obviously hasn't been working. That's good.
The question is, why did it take 5 years to figure out that you can't just recruit for talent and that you need to have a feel for who actually wants to be here, who's actually willing to buy in and work hard?
It's especially surprising given that KO was a "lunch pail" sort of player himself, and that his success in 2013-2014 was largely predicated on that sort of buy-in and toughness (Bazz, Boat, Giffey, etc.). He should have had an appreciation for this from the outset.
