Another thing Smart has that Artest did not is a career shooting percentage of 35.6%.
His strengths are real but we continue to underestimate just how bad a shooter Smart is. He's not just bad, he's historically bad, and so far this year he is worse than ever. Ron Artest was a far superior shooter.
He is a role player and should be paid accordingly but will likely get more, likely by a poorly run team that will be in the lottery for the duration of his contract.
I don't see anyone underestimating just how bad a shooter he is. He is a terrible shooter. He's also a good player despite that. The fact that he is a terrible shooter and will be a RFA probably means no one is going to offer him a contract in RFA this off-season.
You keep asserting that a bad team will throw stupid money at Smart. It's less clear who you think that team will be. Going into next year, only 14 teams project to have over $10 million in easy to create cap space. I'll subtract Houston, New Orleans, Utah, and Orlando as teams that are highly unlikely to actually walk away from their expiring talent to be players in free agency. (Utah is the closest call here since Favors is not a must keep player.)
That leaves just 10 teams. Those are the Knicks, Pacers, Lakers, Sixers, Bulls, Mavs, Hawks, Nets, Suns, and Kings with space.
The Lakers and Sixers are definitely hunting bigger signings and neither is going to throw huge money at Smart anyway. The Mavs are a well run franchise and, considering that they wouldn't commit to Noel, are unlikely to commit to Smart. The Hawks are another good franchise unlikely to do something stupid. The Nets look like they fit this bill too now and are probably looking to maintain flexibility until the contracts they took on this off-season for assets expire in a year.
That leaves the Knicks, Pacers, Bulls, Suns, and Kings. The Suns are a mess and need a PG, so they are a real option. The Kings have money to spend but a silly offer to Smart would take basically all of it. The Bulls have a ton of money but I think they are another year or two of tanking away from trying to start actually building again. The Pacers and Knicks could both get to a Max of about $15 million in cap space, but both are likely to be trying to add talent to help them get to or compete in the playoffs.
The real options for a crazy offer seem to be limited to the Kings, Suns, and maybe the Bulls. The Knicks and Pacers are two more teams that could extend an offer that would force Danny to think about whether it is worth matching, but neither can afford to dramatically overpay.
