Melo is going to be the best player on the market, doesn't mean you just go after whats the best available at the time. Plus Karl is old and probably isn't interested in a full rebuild and his philosophy of coaching isn't that much different from MDA's.
It's not foolish to doubt that a 36 year old man with a sick leg cannot carry a team to a Finals victory. Guys have created this myth that Kobe been fighting through crazy injuries and come back. Kobe has never had a career ending type injury or an injury that would alter his style of play at any point in his career. It's called being realistic. Kobe has had an amazing run but at some point it all ends for everyone.
The market for players and coaches cannot be more different. There are fresh players that come out of the draft year after year. There is no draft for coaches. The coaches that exist in the market are all we have. Either that or look towards NCAA coaches, which I doubt the lakers will ever do outside of Coach K.
George Karl has proven that he can coach to his teams strengths. He had a team full of runners last year, and he excelled at scheming a fast paced offense for them. The nuggets unfortunately lost their biggest offensive weapon in Gallo and they fizzled out real quick.
In 09 he had a much slower team with Chauncey, Melo, Nene and Kmart. These guys excelled in halfcourt schemes and made it to the WCF. Unfortunately for them, they were up against the Lakers.
Like I said, I believe he would be the best option. Out of curiosity, who do u want coaching the Lakers?
Again, I still believe in Kobe. 36, coming off his biggest injury yet, yet I can't help but be in this dudes corner. Call it what u want.
