IF we get multiple young pieces, and IF they work out. Heyward IS a young piece that has shown plenty of flashes and could put it together at any time (he already has in the past).
And unless those hypothetical young pieces contribute immediately, we will be worse than mediocre for at least a year or two. It's all a gamble. Heyward has shown plenty of signs of being a good gamble.
Unfortunately our current contract situation could force us to trade Heyward or Upton. Trading for prospects does work as long as you have the right people picking the players.
If you could get a package of Betts/Owens from the Red Sox I think we would strongly have to consider it.
