I would think you would be happy he could opt out after year 4, maybe save you a year of having to watch him 4 years from now. Also, not sure why it would be so shocking he would have a no trade clause. Y'know, it's kind of funny, but the four guys I can name who have had no trade clauses are Nowitzki, Duncan, Garnett, and Kobe, none of whom I would peg as monsters for it. All better players than Melo in their prime, but still, not necessarily a shocker for Melo to get one under the circumstances.
