I'm perusing the starting pitchers that were good last year....there aren't a lot on non-playoff teams. Especially if you eliminate any with only a year or two in the majors. Other than the Marlins pitcher last year, it's hard to think of starters traded with more than 2-3 years of control left. I think trading is going to be difficult, and pricey.
The Orioles seem intent on tanking for the next 3 seasons or so. How about John Means? Make it a blockbuster and get Givens for the pen and Mancini to replace Cron. Or is Means too big of a risk in not being established enough yet?
