When you say be "good" at teh big league level, do you mean be star players, be productive players, IE Ryan Theriot, or stick round the league for a while due to defensive skill or their teams not botheing to replace them with a free agent who may or may not be a slught upgrade IE Nick Punto. Either way, I think Jay Jackson belongs in the likely catagory, the question is as a starter or reliever. Also, I think that Tony Campana and Matt Spencer belong in the got a chance catagory, and Darwin Barney and Wellington Castillo both appear major league ready, although they''ll probably end up as back up players. Also, Thomas Diamond is in the possible catagory, although he may not end up with us. Oliver Martinez also seems worth tracking.
