The Notre Dame Fighting Irish are in serious need of bodies at wide receiver. The decommitments of C.J. Williams and Amorion Walker from the 2022 recruiting class has put a serious strain on the position group. With newly signed Tobias Merriweather (not enrolling early) the Irish have just 8 scholarship receivers able to play this fall. Three of the eight are 5th year possibilities with another being a 6th year possibility.
So yes... Notre Dame should absolutely be looking at the transfer portal right now.
It gets a little trickier for the Irish.
