There's no doubt that if Jamison is dealt/bought out that there will be a large volume of available offensive opportunities available. I don't think Tristan will initially look to gobble up/have plays drawn for him to take some of those shots. I really don't think Tristan will be confident and consistent enough until he has a solid offseason to really work on his game. I do think that Jamison being removed does help him so he does get some sort of consistent feel for the game, especially by building chemistry with Kyrie.
That's why I have consistently advocated trading Jamison to a team that has another high volume shooter/scorer. I've also been advocating getting an asset back for taking on such a player. I think dealing Jamison to Charlotte and taking on Corey Maggette (with some incentive) is an avenue to explore. I think that two teams that the Cavs should be talking to are Atlanta and Charlotte.
It's hard enough predicting rational, realistic trades with one team, let alone two. But, what about something like this:
Trade with Atlanta and Charlotte
http://games.espn.go.com/nba/tradeMachine?tradeId=88mrsqb
Cleveland trades: Antawn Jamison, Ramon Sessions, and 2012 second
Cleveland obtains: Corey Maggette, Marvin Williams, and 2013 first (POR via CHA)*
Atlanta trades: Marvin Williams, Kirk Hinrich, and 2012 first
Atlanta obtains: Ramon Sessions, Boris Diaw, and 2012 second (CLE)
Charlotte trades: Corey Maggette, Boris Diaw, and 2013 first (POR)*
Charlotte obtains: Antawn Jamison, Kirk Hinrich, and 2012 first (ATL)
*Pick details: (Top 12 protected in the 2013 draft, top 12 protected in 2014, top 12 protected in 2015, and unprotected in the 2016 Draft)
Cleveland picks up an overpaid vet who turns into an expiring chip next season in Maggette, a possible upgrade at the wing (desperately needed) in Williams, and another protected first round pick. The protection isn't anywhere near as bad as Sacramento and is unprotected in 2016, which is fine with me because we shouldn't need a ton of picks of the next few years, I'd rather they be more spaced out. I don't overvalue Jamison and Sessions. I look at this as basically trading Sessions for Williams whilst including the lesser second round pick this year to get Atlanta to send their pick to Charlotte so the Cavs can get the Portland pick from Charlotte. I don't think Maggette by himself gets you anything but an added second rounder. I'd rather combine the assets and try to get a first in this way.
I don't know if Atlanta still has burning interest in Ramon Sessions, but I think he is better than Jeff Teague. I think Sessions can shine if given a legit chance, there's just no place for him here long term and I believe you have to get something for him. Diaw is an expiring that can plug into Williams spot and is versatile enough to do a lot of things for the team. He also doesn't command offensive touches, so you can allow Johnson and Smith to dominate the ball. This move also gets the Hawks below the tax level this year, and saves them the future money owed on Marvin Williams' contract.
Charlotte picks up a veteran presence and scorer in Jamison who has claimed interest in playing for his family before he retires. He may help the team this year (and beyond should the Bobcats choose to sign him to a reasonable contract). He definitely would help fill in some of the scoring that that team needs so badly. He and Hinrich are both expiring deals and don't hurt the franchise. Maybe Hinrich can carve himself a niche on the team? He's certainly not likely to be a headache like Diaw. The removal of Maggette saves the Bobcats money next year and Diaw's departure removes a possible distraction. That coupled with a first from Atlanta should be incentive enough to send the Cavs Portland's future first.
I think this is fair for all three teams involved and does legitimately address concerns that all three teams (and management) current have.
