SAN DIEGO -- Imagine how good this team would be if it ever stayed intact.For now, that's a sight seen only in glimpses, enticing as they are frustrating. The Los Angeles Dodgers nearly ran themselves aground with injuries last June and then, as their health improved, rallied furiously into the playoffs. Now, a mere four games into the season, they're already being tested.A year ago, it was mostly hitters clogging up the disabled list, a murderer's row of hamstring, shoulder and ankle maladies.
