I do believe I brought this up after reading it, but I highly recommend in light of this discussion, The Amazin' Mets, 1962-1969 by Bill Ryczek, covering with welcome depth the composition of the post-Original, pre-Miracle Mets (though those teams are included as well). Included are studies of the remarkable intellectual strength of the '62 pitching staff, the resurrection of Duke Snider, what it was really like to play for Casey Stengel, the forgotten youth movements, the improvement and inevitable fallback of the Wes Westrum Mets, visits with the likes of Don Bosch, Bill Denehy and Joe Christopher and the Yogi Berra/Warren Spahn interludes. A lot of stories I'd never read before, well beyond the myths we know. Ryczek also wrote the definitive portrait of the early Jets, Crash of the Titans, recently updated.
