2011-12: In his first year with the Golden Gophers, Ambroz was a nonfactor. He had eight points in 41 games, netting five goals and setting up three. Just a year after dropping like a face off puck in the draft ranking, Ambroz was unable to silence the naysayers his first year in college.
2012-13: Ambroz played in 38 of 40 games for Minnesota as a sophomore. He scored 9 goals with 7 assists and was +11 with 22 penalty minutes. The Gophers finished first in the WCHA for the second straight year in their final year in the league but ended the season with back-to-back losses. Colorado College defeated the Gophers in the WCHA semifinals and Minnesota lost 3-2 to eventual national champion Yale in the NCAA West regional semifinals.
Ambroz has size and a nice shot, but needs to work on his awareness. He is a big body on the ice and can develop into a great power forward once he learns proper positioning in the crease.
Last season Ambroz improved, which is a good sign. Despite doubling his point totals from his freshman campaign, the 20-year-old still does not play a consistent game. He needs to continue developing his positioning, but may be a career checking line player.
