Road Team versus Home Team

I don't remember a team that seems to favor road games. Why is that? Also, I'd like to know how many runs the opposition has scored directly after an error especially with two outs. It has to be a BUNCH as their were four last night on McManus. All things equal, remove that and LSU wins. THere's been several games where that would result in a win if not for errors. No, McManus mistake is not technically an error but same difference.
