Well one thing is for sure, Marbs is going to be over the hill by the time all our young guys are really hitting their primes.
I disagree somewhat with this Tom. Jason Kidd is 32 after all and still able to lead his team. Marbury has a good 3 years left of his current style of play. If he spends that time, however, learning how to distribute better, lead better, and how to score even more efficiently (ala Billups) he will be able to play with these guys in four years. Remember, we dont' have a lot of high-schoolers, these guys are already 22. In four years, they'll be 26 (JC will be 29) and hitting their stride. If they're all still here, Marbs will know each of their games like the back of his hand and will be able to maximize each of their talents to the fullest. We would, however, need another backup pure PG.
However, while I'm not ready to give up on Marbs like a lot of people, if a good trade came along, I wouldn't say no. That doesn't mean wally for Marbs, or Harrington for Marbs. C'mon people!
