Depending on how you want to calculate it: Position players not in our starting lineup on Opening Day (-Barney, +whatever crap we had at 2B on opening day): 4.3 fWAR, 4.3 bWAR Pitchers not in our starting rotation in April: (-Garza, + Villanueva): 0.3 fWAR, 4bWAR Now YMMV on how you want to calculate what constitues a bench/pen guy vs. a a guy like Chris Rusin who is ~half the bWAR and is keeping the fWAR from being a game below replacement. (Junior Lake being the position player version) Personally, I think it makes sense to look at this way, because bench/pen is really more a matter of depth than anything else. In response to your question, I'd say we should be looking for 8-10 out of those groups. (This way of calculating could be even more difficult to figure next year with an expected Baez call up mid-season)
