My gut instinct says no, but at the same time I would probably say there is a higher probability of injury in those players who leave their feet/crash into walls/etc. more often than those who don't. Realistically though, you can blow out a knee taking a wrong step in the outfield, or tweak a hammy trotting to first base, so in the end I think all of the injuries even out. Obviously guys like Griffey and Edmonds are posterboys for people who have been injured making flashy plays, but we've also seen Griffey get injured on some of the most routine plays he has made. Also, I don't recall Andruw Jones missing a whole lot of time due to a fielding injury and he has made his fair share of flashy catches. In some ways the human body can only take so much punishment, as shown by some of the guys who have broken their arm by just simply throwing a pitch. When the body is ready to go, it goes. Playing all out may speed up that process, but I don't think by not playing all out you could stop an injury from happening if it is going to happen.
