Gonna go 5 starters, 6 relievers, no DH, 8 position players, 6 bench
SP - funny thing is, you could totally exclude about 60 years of baseball history and make a perfect staff from pre-1920 and post-1980 pitchers.
Matthewson, Young, Johnson, Nichols, Alexander........Maddux, Johnson, Martinez, Clemens, take 5 from those, and you're never wrong. However, I think the staff should represent all eras.
RP - obviously we're talking about the 3-inning save guys vs. the 1-inning save guys. Again, a mix is best. Rivera and Eckersley are the obvious guys, but there are other things I'd want - lefties, non-flame-throwers, etc.
My staff:
W.Johnson - what he did for the IP...insane
L. Grove - just great, nothing to criticize
T.Seaver - best of his era, over Palmer
S.Koufax - preposterous peaks
R.Clemens - of the recent guys, combination of wins, Ks, ERA, longevity wins out
M.Rivera - the best
D.Eckersley - video game stats
B.Wagner - untouchable lefty
H.Wilhelm - different era, knuckleball amid the smoke
R.Fingers - started and closed, great guy to have (a la Smoltz)
R.Gossage - multi-inning finisher
C - defense first? Piazza had the most pop, but a defensive position first, like SS
J.Bench - offense + defense = best
1B - surprisingly shallow, in terms of all-time greats
L.Gehrig - obvious
2B - 3-headed monster at the top, can't go wrong with any
E.Collins - great all-around
3B - power vs avg, think it comes down to Schmidt vs Brett
M.Schmidt - take his power
SS - defense-first position, only one choice
H.Wagner
LF - plenty of talent here
T.Williams
CF - like 2B, 3-headed monster, just depends on what you value
W.Mays
RF - deep position, but obvious choice
B.Ruth
Bench - real bench, backup catcher, corner IF, middle IF, 2 OF....mix of R/L, defensive specialists, speed guy, etc.
C - Y.Berra...3 MVPs, great all-around, plus play LF
1B - J.Foxx...righty pure power
SS - O.Smith...best defensive SS ever, could also run
OF - B.Bonds...patient, could run early, could rake late, lefty hitter
OF - T.Cobb...will take his wheels over Mantle's pop
Starting lineup:
1.Collins
2.Wagner
3.Ruth
4.Gehrig
5.Williams
6.Mays
7.Schmidt
8.Bench
