Live Chat: UFC 160 preview, TRT discussion, Josh Barnett-UFC signing and more

A heavyweight title showdown is upon us. I think I speak for most fans when I say watching Cain Velasquez compete is exciting and the somewhat surprising success of Antonio Silva is a welcome departure from the expected. That said, it's hard to get up for a rematch between two fighters where one bathed in the blood of the other in their first encounter.

Vitor Belfort also seems to have whacked the hornet's nest on the TRT issue. His amazing success at middleweight combined with his erratic behavior have made many wonder if we've reached a tipping point in TRT abuse.

And would you look at that? Former UFC heavyweight champion Josh Barnett is back in the UFC to close out the last chapter in his career. I never thought I'd see the day. Actually, I take that back. After years of battling with Dana White in public, Barnett called White 'pretty f--king metal' once UFC purchased Strikeforce. I figured once we hit that point anything was possible.

There's a lot going on, so join me today to discuss all of this and more. In terms of today's chat, anything is up for discussion, but I will lead with this and it all kicks off at 1 p.m. ET.

As is customary, I'll post the video window here as the event draws near and I'll answer any questions you may have if you post them in the comments section below. Be sure that you click the 'rec' button for those comments/questions you believe most deserve a response.
