If Livan Hernandez has suddenly gotten prematurely old at 31, we'll find out. If a fitter Jose Vidro is really a premier hitter again, there will be six long months to document it. If Alfonso Soriano wants to play the outfield in Southeast someday, or if he's desperate to skip town, we'll find out by July. If the pitching rotation assembled by General Manager Jim Bowden is a season-long disaster, then the Lerner-Kasten jury will render a verdict in due course. And if the Nats take a few more 4-1 leads in the 11th, and lose 5-4 (as they did Thursday) because Frank Robinson can't find a way to manage three outs before his bullpen allows four runs, then he'll presumably be a Nats senior adviser next season, not the boss on the bench.
