Area 1: Speed--I think this will improve for you a bit, but not much. Probably the area with the most room to improve. That being said, it is hard to do.
Area 2: AVG--this will get better. Giles, Leiberthal, Lee and Beltran will all hit better from here on out, so you can relax here.
Area 3: Runs--Giles, the Cabreras, Wells, and Beltran will pick it up. You have good power, so that helps because often they can drive themselves in, so overall team lineups aren't too important.
Overall be patient, but you may look to add some speed.
