I always wonder on something like that though -- ok:
1) don't fire Karl
2) fire Wahlberg
is that supposed to somehow automatically make Wahlberg's system go away? Wahlberg was with Karl for years in Denver, then came here and spent a year with him in Sacto. I'm sure Karl knows how to run it, and if he likes it, he would just keep on doing do. After you have already established you aren't going to fire him, what's the pressure you can apply?
P.S. I am also reminded of two things said earlier in the season:
1) back in preseason Vlade told Boogie not to mess with the 3pt stuff, to get down inside. This guy may have irked him all season long.
2) Cousins repeated statements that he was trying to be coachable. Trying to be coachable to me indicates you are doing stuff you wouldn't normally do on your own, but you're tying to be open minded and cooperative.
