This lineup is VERY possible. There is a certin team in the AL East, that in say, four years, if everybody reaches their potential could end up going to the World Series with some pitching. This is a young team, and here are the vets I would compare them to:
1. Kenny Lofton
2. Barry Larkin
3. Ricky Henderson(minus 20-30SB)
4. Albert Belle
5. Jim Edmonds(minus the defense)
6. Jeff Kent
7. Luis Gonzalez
8. Randy Winn
9. Paul Lo Duca
Here's the actual lineup:
Gathright, Upton, Crawford, Young, Gomes, Cantu, Huff, Baldelli, Hall
Outside of the fact that at least 1, probably 2 of those outfielders will be gone, Huff will be gone, they play in the same division as the Yankees, Red Sox and Blue Jays, you would need every player to hit some pretty amazing potential (Young=Belle, Gomes=Edmonds, Cantu=Kent??) and that they don't have 1 solid arm on the entire roster outside of Kazmir...
...yeah, that have a good shot at going to the World Series.
