But that's not the argument, is it? You claimed "no impact prospects ready to contribute". By that reasoning, it's impossible for any prospect "to be ready to contribute" until they've actually done so. Gibson should be ready to contribute by the All-Star break if his rehab goes as expected. Parmelee is already contributing. Arcia and Hicks have a good shot at contributing. No one is claiming certainty about anything, we're simply refuting your statement that "no impact prospects are ready to contribute in the majors next season". There are several who should contribute at some point in the season. I'd be suprised if he's not pitching with the big club by early June at the latest.
