If there's no room for Shields under the UFC's robust Welterweight umbrella, then why not immediately usher him in for a title shot against Carlos Condit? Shields Vs. Condit II? Sounds good to me.
Don't want to have to market both Diaz bros. in same division?
WEC for Nick? Good chance of beating the champ, IMO. Sounds good to me.
Also, Lawler is clearly a better Middlweight than Welterweight and is pretty apparent that he's fair better in the UFC than before.
