Parker makes Cleveland better...but not THAT much better.
Parker isn't that much better than Wally Szczerbiak, actually. He probably has about as much talent as Wally and Sasha combined at this point. So yeah, it's a blow to us in that Parker is no longer an option for us, but it's not going to make the Cavs noticeably better. They really needed Marion, Ariza, or Artest to improve considerably.
The real problem for us is if we don't sign Grant Hill.
Then we're really stuck with Bogans, Barnes, Jones, or possibly Daniels. Either that or make a trade for some wing guys from a team in dire financial straights like the Kings (Garcia / Nocioni) or the Hornets (Wright / Peterson).
