i have a few comments for you (keep in mind i cant access your team link from work so i am basing these comments off the lineups you have posted).
1. i dont like rebuilding an entire team (and losing 2-3 million on an ajones drop) during the season. i do think ajones is overpriced, but if you do draft him, you will especially be distracted by his poor offensive numbers because of his great defense. with a 1 range and -4 arm in cf, you wont see hafner-like numbers at the plate.
2. i dont know what your staff is like, but it does appear that santana is underperforming versus lefties (but who cares since he faces righties 70% of the time or more). may just be bad rolls or something, or a lot of big parks in the rest of your division.
3. ballpark ratings have way too much of an impact on this game. one guy who hits 350/500 in rogers can hit 300/400 in petco and 400/600 in coors. its just plain stupid that a park can account for roughly 300 ops points, but expect this going in to a petco team.
4. besides clark (im assuming tony clark) i am not very fond of your lineup. it doesnt seem that besides him and magglio that anyone can drive in runs. i mean i look through your lineup and there 1 good batter and only 2-3 other respectable hitters (in my mind). maybe if you are facing 80% lefty pitching you would be doing better. but having cano, redmond, agone, youk, lharris, and singleton against righties is totally unacceptable.
5. in addition, i dont think the batting is good enough to justify the poor defense. there is never any reason to get rid of ohud, especially for cano (whos terrible). if you are a petco team, i would go for better defense than this.
those are my 2 cents...hope it helps.
