At this point i prefer sentimentality as well. I certainly would tend to not trade Ray to a team he wouldn't enjoy.
However, others have made good points, and it's a discussion worth having. Ray definitely dropped off a bit this year, and really looked ragged in the playoffs until the finals. With that finals performance, his stock may be a bit artificially inflated. We got very lucky with injuries to our stars this year, and we may be thinner next year as brown and cassell leave, and probably one of house/posey as well. Age wise we are similar to where the spurs are now (just with one title to their 4), and they've really started to look slow; the consensus is they may not have balanced bringing up youth while contending. It's a very tricky question to figure out when to cut loose a great player, well liked by teammates, in order to think a couple years ahead and avoid sticking with a guy once he's over the hill and has diminished production and trade value.
Turning my eyes to the general following of the upcoming draft, I was intrigued by this nugget from Chad Ford:
The Phoenix Suns have put Leandro Barbosa and Boris Diaw on the table in attempts to either move up in the draft or secure another veteran to play alongside Steve Nash, Amare Stoudemire and Shaquille O'Neal.
"I think our needs are pretty clear," one Suns insider told ESPN.com. "We can't ask Grant Hill to play 40 minutes a night, and Barbosa isn't really a point guard."
Considering that Allen is still considered a better individual talent than either diaw or barbosa, and considering that the latter two are under contract a year longer than Allen, I was thinking:
Barbosa, Diaw, #15
for
Allen, #30
This would knock about 2 mil off payroll (4 mill with tax), give us a wider spread of contracts, instead of 3 max's and small ones, would satisfy the pg minutes rondo can't play, would allow us a better chance of nabbing a useful rookie, would make the C's younger, and provide an interesting athletic and versatile player who can defend and likes to pass the ball in diaw.
From Phoenix's side, they are all in with Nash and Shaq. They'd love Ray and his distance shooting, and Ray might enjoy playing with those two.
