Let me put you in a broken down Ford Taurus with mismatched wheels, a misfiring cylinder, catalytic converter problems, a couple blown fuses, and busted steering linkage. Now let me drop you onto an active NASCAR track in said car with a pit crew that hasn't worked together for a season. Tell me how you're going to win the race.
There are some really boneheaded things going on, I agree. If the ship doesn't appear to be righted or heading in a good direction by Year 3 then I will definitely be a supporter of finding a new head coach. Until then, let's let the guy finish this race and fix the car. Long term success shouldn't be secondary to short-term gain.
And back to the topic. Oku worried me from Day 1 with his signing day (or lack thereof) antics. I've quietly hoped for the best, but with some lingering doubt as to his devotion. I hope that he proves that doubt to be unfounded.
