I'm definitely no expert but there's two sides to it imo. His stats in college show he was never really good enough. A lot of surprise he got a shot at it I think. 66% when the average in the NFL would be what high 90s?
Secondly, he cost them 2 pts, but their defence gave up 33 points in the 4th quarter alone. That's a shitshow and imo the real story but easier to blame the Irish kicker...
I had a look on X after the game and most was just vile abuse but more considered posters seemed to be of the opinion their recruitment and general management is a shitshow and having a kicker at his level exemplifies this.
