I agree, a good-looking offense, especially when Mauer comes back from the DL, but you can do better than Renteria at SS.
Everything I've read says you can't have too many SP's on the bench in an H2H league, consider moving Ankiel or Griffey in exchange for some decent pitchers to round out your rotation if you can. 6 OFs might be more than you need.
With Hamels and Verlander as your top two SPs, it is a little riskier than normal. Hamel's slightly worsening K/9, FIP, and BABIP would put him at the bottom of the 1st-tier SP group. The Tigers' good defense should help out Verlander this season, but he's good, not dominating. Volquez is still developing and if he can keep up production like that of his 1st half last season, you should be golden. However, I like having the consistency of Lowe and Weaver to balance the relative risk you have at the top of your rotation.
With K-Rod and Heath Bell it looks like you have saves on lock. Even more so if Fernando Rodney takes over the closer's role in Detroit.
