1. Do you think the team must do something to upgrade its shooting heading into next season?
Yes, but there is no blockbuster move to be made right now IMO. I don't think trading Iguodala would net the max value right now so I would sign him (if the price is reasonable). Personally, I would wait until the trade deadline nears, then see what's out there for big moves. If we move Miller at the deadline, maybe we find a 3pt shooting PG or maybe a 30 MPG backup SG/SF that can help in return for Evans/Smith/whoever.
2. How much can we count on improved shooting from players on the roster, and how long will it take to see this improvement?
Very little - guys don't become really good shooters overnight. %'s may go up a tad, but no one is likely to suddenly scare opposing D very much from deep.
3. What kind of moves would you advocate making to upgrade the Sixers shooting? Should they move Miller, Lou or Iguodala, or look for a less costly fix through FA or trading Evans?
I would not move Miller or Andre right now unless it's considered a major upgrade. It has to be more than just a guy who can shoot.
Is there a PG replacement for Miller out there right now...Hinrich, Felton, Mo WIlliams? I would keep Miller over all those guys right now. If you can get those guys now, they are likely to still be available at the deadline so you can re-evaluate then. Let's just play it out and see how the current major pieces play together.
Is there a solid SG that we can get for Iguodala right now...J. Richardson, Hamilton, Redd? I'd consider the first 2 guys, but not 100% sold. Redd I would pass on based on the contract. He's way overpaid.
As for the other guys, I would obviously move Evans or Green for a 3 pt shooter (mainly Green since I would not be comfortable with 2 young guys - Smith and Speights - as the primary backup PF/C's). Can we get a shooter for Green? Doubtful. Not sure I would move Lou unless it's an obvious shooting upgrade? Who fits that profile and could be available? I don't see anyone right now.
Personally, for now, I would just look to find a veteran SG/SF who can be had at the minimum to provide some bench shooting. Also, take a shot on one of the undrafted rookies who can shoot. Basically just a minor tweak or two. A guy who probably won't play that much.
As for cheap ($$ wise) trade targets, I really like Morris Almond and Marco Belinelli. Can either of those guys be acquired for Jason Smith? If so, I do it in a second. Redick is an interesting option too..not sure I would do Smith for him, but it's close. The Evans for Matt Carroll thing is a decent idea...same with Evans for Radmanovic. Basically just trading one flawed player for another. Martell Webster is a guy who could be expendable in Portland...we have anything to use to get him?
Here's an interesting thought. Let's say Phoenix bombs this year (maybe Shaq goes out with a major injury) and they decide to blow up the team. Any chance they may take Miller's expiring deal (and something/someone else) in return for Nash. Now that would be the perfect PG for this system (really any system). He's only under contract for 2 more years so the age thing isn't an issue for me. Gives us 1 year more than Miller does to find long term PG.
