While he's still a bit under the radar, the 6-foot-7, 280-pound offensive lineman is getting noticed.
Senn, a class of 2019 recruit, participated in six camps during an 11-day stay in the U.S., including Sunday at Colorado. As he did at many other stops during his U.S. tour, Senn left Boulder with a scholarship offer.
"I talked to coaches in advance about how interested they are, because I had to book three extra flights," Senn said to Buffzone in an interview on Twitter. "Everything was depending on my performance at the camp. I had a good practice and was really hoping afterwards that the coaches liked it too.
"They told me that I have the frame, the size of playing my position at a high level. And they told me that they liked my competitive attitude."
So did other schools. During his trip, Senn also picked up Football Bowl Subdivision (FBS) offers from Akron, Buffalo and Connecticut. He also received Football Championship Subdivision (FCS) offers from Dartmouth, Holy Cross, Lafayette, Maine and Towson.
By early Tuesday, Senn had completed his long journey back to Austria and was in the very early stages of considering each of the schools that have offered.
"I'm still overwhelmed not only because of CU but also because a lot of other impressions I gained during my first stay in the States," he said.
Senn, who turned 18 on April 23, has been playing for the Swarco Raiders Tirol in Innsbruck, Austria, for the past two and a half years.
Senn said that Bjoern Werner, who starred at Florida State before a four-year career in the NFL helped Senn put his recent trip together and get in touch with schools.
