Rios is a quality player, I like this potential acquisition for many of the reasons Guacarock said.
He's only 33 this year, he should be fine for this year and next. Beyond that, there's Winker, etc.
I'm not upset about the money, it's not a long term contract. Knowing the Reds, they will get some salary concession in any deal with Texas.
If the Reds do this, they still need to upgrade SS by at least .100 OPS points for next year, if not more.
