With 10-day contracts as an option, the Suns have a variety of ways to improve.
Needs: Pretty much depth at every position but the wings. However, one thing I think the Suns need is a guy like Brandon Roy or Danny Granger who can take over a game by scoring from everywhere and making key defensive plays. Amare may seem to be that guy, but I'd prefer the main guy to be someone who can hit from downtown and more versatile defensively. Obviously, there's no one out there like that, but I'm jus' sayin'.
Actual guys to get: Courtney Sims, Darius Miles, Jannero Pargo
These guys could fill the last 3 spots on the roster and combine to provide depth at all positions, 1-5. Sims, a 6'11," 230-pound, 25-year old, in the D-League. He is easily the best big-man in the D-League. He's numbers are phenomenal - (per game averages) 22.7 points, 12.5 boards, 2.7 blocks, 58.5% from the field. I've never seen him personally, so he might just be an Amare-esque defender (big blocks but not much else) - or he could be like Camby. Not sure. Either way, he adds frontcourt depth, and we might be able to catch lightning in a bottle with this guy.
Darius Miles is an NBA veteran who hasn't really played a meaningful game for 3-4 years. That said, he's athletic, with the potential to be a solid player. On the plus side, we could pick him up off waivers, and even if he sucks, play him twice, and screw over the T-blazers. Now, they're a good team and haven't really done anything wrong to Phoenix (unlike the Lakers/Spurs), but making another contender worse makes the Suns better.
Jannero Pargo is over in Russia playing, but has made some notions about coming over for the right amount of money - I doubt it'll be over $3 million for the rest of the year. Pargo was a fine backup point guard for the Hornets last year, and could do the same for the Suns this year. He can shoot, handle, and defend. Unfortunately, I can't seem to find his stats in Russia.
