For a long time, it was thought that Howard has no interest in playing for Boston. Now, we're hearing it right from the horse's mouth that there's interest. Also, we're reading that Howard talks often with Bill Russell (and I'll bet Russ isn't waxing about the good old days when he coached Sacramento).
If Howard wants to go somewhere to win, and form a Big 3, like Lebron did in Miami, the opportunity is in Boston. Pierce is older, but the guy is still one of the best wings in the league. Rondo is the top pass-first PG in the league and the best defensive PG in the league.
That's about as good as it going to get for Howard. He can go to the Nets and play with DWill and a bunch of scrubs (especially if the Nets trade for him and give back Lopez). The Lakers won't trade both Bynum and Gasol for him, although it's not a stretch to believe that Howard could force a S and T to the Lakers for Bynum this summer.
The dream scenario for the Cs would be to sign Howard as a UFA this summer, and then get KG and Ray Allen to sign vetmin deals to play for another championship. Garnett and Ray Allen have made enough money for 10 lifetimes. Would their pride allow them to play for the minimum? Shaq did it, and he's the highest paid NBA player ever. If Bass doesn't opt out, Jeff Green agrees to a one year cheapie deal, and a talented bench PG can be had on the cheap (KG pal Billups perhaps?) the Cs will have the best rotation in the league.
The dream scenario for the Lakers would be for Howard to force a sign and trade there this summer for Bynum. Either scenario puts Howard in a great situation to compete for a title and get more ensconced in the spotlight he so desperately seems to need.
