Wanted to get back to this. My take on LF...
1. Ted Williams
2. Barry Bonds
3. Stan Musial
4. Rickey Henderson
5. Joe Jackson
6. Manny Ramirez
7. Al Simmons
8. Ed Delahanty
9. Carl Yastrzemski
10. Willie Stargell
Musial is intriguing because you could realistically put him as a first baseman or a right fielder. He played over 1000 games at 1st, but about 1800 in the OF with more than half coming in LF. So I'm fine with leaving him there. The difference between Williams and Bonds for the top spot is really kind of thin. Just from a counting stat standpoint, it's still remarkable where Williams could've wound up had he not missed three years due to military service. If he just had his average season for each of those, he ends up with in the neighborhood of 620 career homers AND doubles, and 2200 RBI. Since these would have been his age 24 through 26 seasons, it's reasonable to believe he had a good shot at going even beyond that. Still, his last season might be his most remarkable. He only played 113 games, but hit 29 HR with a .316 BA, .451 OBP, .645 SLG (higher than his career mark), 190 OPS+ (equal to his career mark) and 4.8 in oWAR (3rd in the AL). He was 41 years old.
Some other guys that I feel were close: Ralph Kiner, Billy Williams, Tim Raines, Goose Goslin.
Among actives, I considered Berkman, but can't put him ahead of any of the "close" guys. Matt Holliday is the most interesting case of the actives. If he continues the way he's going there are going to be some heated debates about his HoF candidacy. Not sure he could crack the top 10, though. Another is Ryan Braun. We'll have to wait and see what kind of player he is post-scandal.
