Are you even aware how idiotic that comparison is? Simmons at $15m is obviously more valuable than Markakis at $11m, which is precisely why the return for Simmons is now the best prospect in the entire Braves system.
I swear, some people just can't seem to take logical steps so I'll spell it out for them.
Simmons value stems from all world defense and the potential for improved offense, all at an affordable price. If his defense falters a bit, and his offense never improves beyond the sub 700 old guy he has been to date, suddenly he isn't that valuable at $15m.
The Braves obviously feel the risk/reward of a potential Ace is worth the risk/reward of Simmons.
I'm aware of all that. I also feel the Braves traded Simmons for more payroll flexability. We are becoming the Marlins.
