In fact, he was extremely productive when he played on those 'We Believe'- Warriors' teams alongside Baron Davis, Jason Richardson, Stephen Jackson, Matt Barnes, and Al Harrington. While we tend to think of him as an inefficient gunner, much of this is the result of being forced into the primary scoring option for the majority of his teams.
He's less than a year older than Gay and has been fairly durable throughout his career, despite consistently finishing near the top of minutes played per game.
Further, at his best, Ellis is better than Rudy Gay at his best his career PER, True Shooting %, and Effective Field Goal % are all better than Gay's. Mayo in free agency (for the record, I think we should let him walk or try to get something in a sign-and-trade), Ellis replaces OJ as both a PG/SG as well as a microwave scorer. I'm begining by elaborating on an idea that I proposed in the comments of another thread: Rudy Gay for Monta Ellis. Thus, we begin our Rudy Gay Trade-a-Thon where the SOV writers offer up various trade proposals.
Grizzlies' fans are more than happy to trade him, but only if we get pieces back which help us win now. If you've been following the NBA or the Grizzlies at all, then you'll know that Memphis forward Rudy Gay is one of the major trade targets in the offseason for a number of teams.
