bert is ready, a kicker, 1-2 TE's..one for blocking and one for catching, 2 DT's as it appears a few signed a few years ago are not going to pan out, 1 WR but only if Malachai level and potentially 1 RB but only if Price goes pro and the RB would be a clear #1. Naturally, some guys could leave, but I don't see ND needing to dip into the portal for much outside of quality depth.
With that said, I see ND going hard after the RB from South Carolina unless Price has communicated he's staying (which I think he should), 2 big bodied DT's, 1 TE and a kicker. I could see a serviceable back up QB and blocking TE coming in from the Ivy Leagues or a DII school.
keep in mind, unless the player is a Freshman or graduate, it's tough for ND to bring them in. The pool for ND gets small quickly.
