Looking at the scholarship numbers (including all the fifth years), we currently have thirty-nine on Offense, forty-eight on Defense and three on Special Teams.
Without Counsell, Grace, Rabasa and Hounshell, the Irish would be at forty-four on Defense. With two less LBs (Counsell and Grace), ND would have twelve LBs. With one less DE (Rabasa), DE would be at eight. With one less DT (Hounshell), DT would be at nine.
So neither DL nor LB are positions of need.
As for transfers, not considering transfers for fifth years, 2014 saw only one undergraduate transfer (Sykes). 2013, however, saw four undergraduates transfers (Ferguson, Neal, Kiel, Badger). 2012 saw three undergraduate transfers (Shepard, Lynch, Prestwood). I think 2015 will be a lot like 2014 with minimal undergrad transfers.
