Last three years, Moustakas 2.0, 2.4, 2.8 WAR, 113, 105, 113 RC+
At 31, he's unlikely to improve on that, and might decline the last couple years of his new contract.
Last three years, Segura, 2.9, 3.7, 2.3 WAR, 111, 110, 92 RC+
At 30, he has 3 years at $14M, not 4 at $16M
Last three years, Gregorius, 4.1, 4.7, 0.9 WAR, 109, 122, 84 RC+
At 30, ??? on new contract
Don't think Phillies have missed out by not signing Moustakas.
