"I thought I was done taking (official) visits," said wide receiver, cornerback Brad Mueller.
"I was pretty set on Wisconsin and Boston College but the defensive backs coach from both schools have left for other schools.
"I haven't ruled out Wisconsin or Boston College but I might visit Arizona State this weekend.
"Duke is even back in it now and I'm still looking at Iowa and Purdue.
"I should know where things stand by Wednesday (1/8)."
Muller, a 6-foot, 170-pounder, from Mars, Pennsylvania runs a 4.27 40-yard dash. He was named 1st team all-state by the Pittsburgh Post-Gazette as well as the Pittsburgh Tribune Review.
