They're "confirmation" threads. n00b asks a question but really just wants his opinion confirmed. If/when that doesn't happen, he becomes defensive about his strategy and will go to great lengths to defend it. To SJP's credit, he seems to have done quite a bit of research and even admitted that he might have learned something from these 5 pages.
But he still made a horrible deal as soon as he could submit it. I think he'd have been better served to wait until FA started and, if nothing suitable came along, kept the two pitchers. I assume he intends to turn that 22m payroll into 11m in prospect. But he only has 14m in IFA scouting so there's no guarantee he'll see the best. Most likely, he's get a couple level 2 IFA at 8-10m each.
