Yes, but Lee is still one of the 10 best paid players in all of baseball I believe. So while he didn't take the highest offer, he didn't really do the Phils any favors so to speak with the contract he agreed to.
If the Braves offer a similar amount per season to the offers out there, I fully expect Mac to come back. If we lowball him (as we often do with our free agents) then I fully expect him to move on.
Never understood why we are so reluctant to pay our own free agents what it takes to keep them around, but we bid against ourselves in cases like Lowe and Upton.
