point by point
1: I believe grad transfer kicker and Vinson are both out of eligibility after this year, so ND will have 3 next year. ND projects it will have the room in 2022, so why not?
2. Agreed. Kelly did this as a way to pay Powlus more without paying him more,
3. I don't think they are recruiting a 5th RB just to have a 5th RB. They are recruiting the kid b/c they think he's the best player available, regardless of position.
Re: NT ND will be 5-deep at the position in 2022. Given that NT typically comes off the field on 3rd down, that's plenty of bodies.
Re: WR, ND really needs more guys for the 2023 team since the 2022 room includes 4 5th/6th year seniors that will leave. They don't need a grad transfer unless that guy has multiple years of eligibility. They pushed for Lowe, but didn't get him.
