This is from Mariners Central, a respectable Mariners blog.
"What it's going to take to get Griffey over here is the biggest question. Would the Mariners give up Wladimir Balentien or Jeff Clement? I don't know. The Mariners would probably be hard pressed to part with their top prospects. Other than those two, guys like Phillipe Amount and Carlos Truinfel come to mind. Cha Seung Baek and Jeremy Reed apear to be extra parts, and are still young and have some potential, so maybe Baek, Reed and another high-ish level prospect would get the job done?"
If the Reds could get a combo like that for Griffey, it would be the best of all possible worlds. He can go home to finish his career where he started it, like all great HOF's, Mays, Aaron..., and the Reds could get some decent prospects in return who can help out rather quickly.
