What to watch for on signing day

ESPN.com's RecruitingNation takes one last look at what to look for Wednesday, when recruits officially put pen to paper to join their new schools.

Jared Shanker wonders if Notre Dame can put the finishing touches on the 2012 class, writing:

The Fighting Irish already have a top-10 class, but they need to add a few more pieces, specifically on defense, to really make this class stand out. The Irish missed out on one of their top targets in ESPNU 150 prospect Arik Armstead (Elk Grove, Calif./Pleasant Grove), but they are not giving up on fellow ESPNU 150 recruit Ronald Darby (Oxon Hill, Md./Potomac), who recently decommitted from the Irish. Four-star linebacker Ken Ekanem (Clifton, Va./Centreville) could sign with Notre Dame if the staff picks up interest and is comfortable with his knee after he tore an ACL during his senior season.
