Position: Tight end
Weight: 245 pounds
Numbers: Irwin has caught 12 passes for 205 yards - both career highs - with five of his catches going for more than 20 yards. Those numbers represent the most catches and yards by a tight end in head coach Mike MacIntyre's three seasons as head coach.
Potential impact vs. Utah: Irwin has become a more frequent target since backup quarterback Cade Apsay took over the offense. He and his fellow tight ends could play a key role in the CU offense moving the ball against the Utes.
He said it: "I'm used to blocking and it's fun to get out there and catch some passes, but I just do what I can to help this offense and this team."
