You can't get a top starter by trading prospects #10,11, 12, 13 and 14.
My guess is any such trade would have to meet one of these criteria:
1. #2 Casas or #1 Mayer plus 1-2 others between 10-20.
2. Two from #5 Bleis, #4 Yorke, #6 Rafaela or #7 Mata plus maye a 10-20.
3. One from #5 Bleis, #4 Yorke or #6 Rafaela plus two from #7 Mata, #8 Walter, #10 Paulino, #15 Wikelman
I'm not sure Bloom has it in him. It might take convincing from Kennedy or someone else.
I am convince of one thing: we can't get way better without adding a top pitcher as just the first of several pitching additions or bring-backs (Wacha, too?)
