Everyone is entitled to his or her opinion, and my opinion is that your's sucks.
1-- "Corbin's strength is offensive sets." Do you even watch the games? This team is the worst Jazz team in running offensive sets since the team moved to Utah. Harpring has been caught on the air wondering if this team knows how to run an offensive set.
2-- "Perhaps he is a little behind on deciding substitution patterns but that is easier to pick up then offensive sets." A little behind??? This is a guy who has NEVER made a strategic substitution to start the second half. If you and your assistants can't figure out what to do during half-time, then you sure as hell can't figure it out while the game is being played.
3-- "I still maintain that the stuff he isn't good at can be learned by anyone." Coaches are not drafted, they are hired. They're supposed to know how to coach the game by the time they become Head Coach. Sure, they don't know it all and they'll continue to learn the nuances until they retire; but a rookie coach damn well better have a steep learning curve or he has no business being a head coach. Corbin has been the head coach for going on two years, and he's no better today than when Sloan quit.
