IMO, I think Richie Martin gets some attention and love on here because he was a former first round pick by an organization who knows what they're doing. And then we got him in the Rule 5 draft so it's like people want to cling to the idea that he might be able to turn himself into something.
Getting a player for next to nothing when another organization (especially a smart one like the A's) casts them off and having that player turn into something is, like, the OH collective wet dream.
That, and he's an athletic looking dude. 6 feet, 190, looks like he should be able to be fast and agile, probably cover a lot of ground in the infield.
I think those are the reasons people are still willing to give him a chance, as silly as they are. IMO, he's nothing more than a backup infielder. But I don't really understand the reasons for thinking that he can develop into more than what he's shown to be.
