the timeline is:

1) ND told Angeli he'd be the only QB they take in 2022 class.
2) Angeli committed to ND.
3) ND is now pursuing a 2nd QB in the 2022 class.

Clark would have been an inexperienced, injury-plagued senior in 2022...I do not see how that would have anything to do with chasing Howard, as he (and Angeli) would be mere freshmen in 2022. I doubt they were counting on Clark to break into a Pyne, Buchner, Angeli depth chart in 2022 when they were making promises to Angeli.

Clark did not practice in the spring. The talk was of a medical hardship at that time.
