You have to remember, Latos has less Major League starts than Homer, and is younger than Mike Leake. I have my concerns about him long term pitching in GABP.
As for Bruce, he will be fine, he's a streaky hitter, when he's hot he will carry the team for a couple of weeks, when he's cold, well he could cool off hell.
As for another bat, the bench absolutely blows chunks. Everyone of the bench players except the 2nd catcher, could be improved. What I would like to see happen is Ludwick get more consistant playing time, the guy is clutch and he hits for power. I think he could be your 4 hitter, and move BP back to leadoff. Heisey is a better pinch hitter and late inning defensive replacement anyway. That helps the bench. I've also heard they are looking at Carlos Quentin, which if he's actually healthy and ready to go, I take a fly on him all day.
Cozart is solid, but not a leadoff guy, Stubbs actually is doing pretty well in the 2 hole, he's bunting more (still not enough), Votto is Votto, the best pure hitter in the game, BP is not a clean up guy, get him back to leadoff, Bruce is in the right spot just streaky, Frazier is coming along nicely, I hate to think they are going to sit him when Rolen is back, he'll just get hurt again, Heisey/Ludwick, see above, Hanigan, wow this kid can play for a fringe catcher, he is under-rated.
The pitching is obviously pretty good. Sure the rotation has some questions, but the pen is money. Chapman will be in the pen at a minimum this season, they aren't going to switch him midway, but you get a healther Masset and Bray back, you actually have some trade bait. I probably send Hoover down, to continue to develop, but then someone else is expendable, who is that? Simon has been more than solid, I think it's probably LeCure if you don't trade one that has value.
Just my quick look at the team as it stands now.
Hear them Bengals growling mean and angry.....
