"Auston Matthews, a dynamic center projected by some to be the first overall pick in the 2016 NHL draft, is accelerating his academics at the U.S. National Team Developmental Program with an eye toward being eligible for college in 2015-16. According to sources, he's told acquaintances that UW is one of the schools he's interested in. The NTDP under-18 squad played the Badgers in Madison in December and Matthews scored two goals en route to a 4-1 exhibition victory."
