2014-15: Mantha did not make his pro hockey debut with Detroit AHL affiliate Grand Rapids until November after suffering a broken tibia in a rookie tournament game in September.

Mantha is purely and simply a goal scorer. He has a great frame that he uses to fight through traffic, solid puck awareness and offensive positioning, all topped with a heavy wrister that he can fire quickly and smoothly. For a player of his size, he skates very well but he needs to keep his feet moving and work hard on both sides of the puck. Mantha is does not mind physical play and will willingly engage in battles, but can sometimes be goaded into undisciplined penalties.
Mantha made his long-awaited NHL debut with Detroit late in 2015-16, appearing in 10 games with the Red Wings before being returned to the AHL's Grand Rapids Griffins. Like other skilled young scorers, the 21-year-old continues to evolve in the other areas of his game and as he becomes more consistent he should see a larger role with the Red Wings.
