Welcome to the Cafe!
Just as an aside, it's a good idea to post things about your league, like how many teams, roto or H2H, scoring cats - helps us to give better advice!
As it stands, I think your hitters could use a little more speed, and I am not at all confident about Griffey this season. Wilson at SS is probably not the best you could have. But the rest is good.
Decent pitching staff, with several guys who could be primed to have a big season. Certainly capable of competing, I think, but I don't think it's a championship team.
