Well, if we'e talking the 1976 set:

1b Gehrig
2b Hornsby
SS Wagner
3b Schmidt
OF Ruth
OF Cobb
OF Williams
C Bench
RHP Johnson
LHP Grove

we can also toss in Nolan Ryan, Tom Seaver, Rich Gossage and Dennis Eckersley to fill in the rotation and bullpen.

From what I've seen, I think I'd pick T206 because of the pitching (assuming the whole rotation mattered not just one righty and one lefty). Cracker Jack probably second. A 90s set with Clemens, Maddux, R Johnson and Martinez would be high too.
