Vanecek joined the Florida Panthers and the trade deadline last season and served as the backup to Sergei Bobrovsky during the run to a Stanley Cup Championship.

After winning the Stanley Cup with the Florida Panthers last season, Schmidt has secured a three-year deal worth $3.5 million AAV with the Utah Mammoth. The 33-year-old Schmidt averaged 16:32 time-on-ice and scored 19 points (5G / 14A) in 80 games last season.
Entering his age-34 season, Tanev will look to prove he is still an intimidating force as he joins the Utah Mammoth on a three-year deal worth $2.5 million AAV.
