Paul Creighton (STC / TE Coach) on Kielmeyer: “We are fired up to have Tyler join the Tight End room! Tyler is a gifted athlete that will bring the physical demeanor needed to play in the Big Ten. Not only does Tyler bring a lot to the table on the field, but the first two-time team captain at his high school in 25 years will also bring a lot to the team off the field as well. His leadership skills paired with his athletic abilities make him a very exciting addition to the Wildcat family.”
