Out of all those mentioned I expect only Ricky to perhabs sign a new 1-year contract. I don't know enough about Cobbs but if he is deemed to have potential probably him too. I think Ronnie has to prove himself next season in order to warrant an extension.
Are you saying that Ronnie needs to prove himself by staying healthy for a year or ....?
Well a bit of both, I doubt they will throw a multi-year extension to a player who has had 2 relatively big injuries in 3 years and then gets another. Or if he stays healthy but then produces sub-par is another scenario. :)
