I initially read the title of this post as 'Odom and Ladyboy both signed'. I wonder what that says about me...
Anyway, I'm kind of pleased Miami isn't signing more players at the moment. For starters, there will be draft picks to play (and pay) and also, it's unrealistic to expect the worst team in the league to go to being good the following season. I'm sure there are examples of it happening but, more often than not, they're pretty bad again (See 'Oakland Raiders' for reference). It'll take a couple of years to fill the roster out properly. Obviously there will be players filling the roster in number but some of them are just placeholders and it'll take a couple of years of drafting and free agency to turn the team round. Please be patient people.
