Donegal won't beat Dublin in the All-Ireland semi-final on Sunday if their scoring rate doesn't improve.
That's according to former Donegal wing back Kevin Cassidy.
The 2012 All-Ireland champs have averaged 1-13 per game this season.
Cassidy doesn't think that's good enough to stop the Dublin juggernaut
Cassidy was with Barry Cahill to promote the Croke Park Classic between University of Central Florida and Penn State this Saturday.
