Yes. Under Wren's administration it occurred during last offseason's arb discussions. Hart was involved at that time as well in the structuring of the long-term extensions for our guys. Heyward wanted something well north of what Freeman got and it became clear both sides felt there was no way to "bridge the valuation gap" (i.e., Heyward wanted to be paid like a premier player; the Braves were hesitant because they did not want to pay him like a premier offensive and defensive player when his bat hasn't yet hit his once projected ceiling)-- hence the two year arb buyout just to get into this offseason. All further extension talks were tabled.
Then John C and Billy Ryan (among others) had ongoing discussions over the past month with Casey Close at Excel. Casey was adamant that any reasonable offer needs to start above $220 and even then Heyward was tempted to test the FA waters. There was also discussion of an opt out. The Braves still did not feel he was worth that much (I have no indication as to what they did feel was reasonable, but I do know it was north of what they agreed to with Freeman) and that was that.
What do you want them to do in light of same? It was VERY clear that Heyward wanted top dollar and there was never any suggestion or offer that he would take any form of a hometown discount (on either AAV or the years) to stay here long term.
