I don't think they are necessarily 'critical' to a teams success either, but something has to be said for the non-measurable attributes speed creates like annoying the crap out of the opposing pitcher and him throwing a fastball that catches too much of the plate. Also, what can be said about players like '03 Lofton, '05 Damon/D. Roberts and '05 Podsednik directly leading to a teams playoff success? I'll assume you mean '04 with Damon and Roberts (since that was the year the Sox won it all) and give you each guy's numbers for that season: Lofton (with the Cubs) in 2003: 327/381/471 Damon in 04: 304/380/477, 20 home runs Roberts (with the Sox) in 04: 256/330/442 Podsednik in 05: 290/351/349 The answers to your questions are: Lofton and Damon were shots in the arm because they got on base at over a .380 clip, and slugged nearly .500, which is pretty good for a CF, not because of "situational hitting" or stealing bases. (For Damon you also can add in the fact that he hit 20 homers, which any team can and should take out of their leadoff man or CF every time). Roberts probably hurt the Sox more than he helped most of his time there except for that one stolen base, which clouds everyone's judgment on him. Podsednik was no more than average for a leadoff hitter, and when you factor in that he was only 59/82 in SB (72 percent), his running around probably hurt the team more than it helped. Oh, and his .700 OPS was absolutely awful (AWFUL) for a LF. The fact that he is largely credited with that team's success is one of the biggest jokes in baseball history.
