Whelan, Povse and Moore give us a lot of AA-ish/AAA-ish guys who are, right now, able to get MLB hitters out and not get completely hammered. One of those guys proves to be a valuable MLB starter, maybe two. That might be likely.
Get three and you hit the Trifecta.
But we're deep now.....as soon as we trade for that St. Louis arm! :)
