Could Brown + Hembree + Belt + Arias get us Altuve? Probably still no but it's a bigger offer.
I don't see Houston trading him much the same way that Bean refused to talk about weeks in their fire sale - He's a fan favorite.
That being said, he is the same kind of hacker the Panda is. Except this kid is like 5-5, and that's being generous with a few inches, so his power potential is limited. Simply not worth giving up Brown, Hembree, AND Belt imo.
Arias is the best option there, and he's free...
