No chance Houston bites. Even if JO plays well, the last thing they need is another injury prone center, who is going to eat into their cap space this summer.
I think they could consider moving Battier for Perk, if they see him as a guy they will sign going forward (although not sure the C's would do it), but JO would just be salary filler and a stopgap with a bad contract (at least given their salary situation), and Bradley has little to no value to put it over the top.
