For the last few years, when the ZiPS projections come out, I do an article using those projections to figure out an overall projection for the upcoming season. This isn't a simple projection where the entire team WAR is added up (which isn't advised in the projection write-ups), but instead a method of projecting the current roster, and using ZiPS to determine the projected playing time and the WAR that each player will receive.
Compared to other projections, this one usually runs high. That said, it has been much closer to projecting the team results, since it has always come in at or under the actual team results.
