A starter on your favorite team's staff will get injured this year.
OK, sure, the odd staff stays healthy all year -- that's just the law of probabilities. But the percentages also say that it's more likely that the average staff suffers an injury or two before the season is over.
Jeff Zimmerman's research on FanGraphs shows that any starting pitcher who started a game last season has a 39 percent chance of hitting the disabled list this year. That number changes based on their health to date, and their age, but the lowest percentage likelihood in his projections still doesn't dip below 30 percent. The consequence of this reality is that teams use more than five starters -- last year, the average was 7.4 starting pitchers with more than 20 innings pitched per team.
Some teams are equipped for the inevitability of injury, and some aren't. Let's look at three contenders that could list rotation depth as a strength, and three that might find themselves reaching for antacid by the end of the season.
Depth as strength
There might not be a better team to describe this phenomenon than the Braves. They could have two injuries to their starting staff before the season begins -- Tim Hudson, Jair Jurrjens and Tommy Hanson have all had issues in the past six months, and more than one of them might not be ready for Opening Day.
