Jon Cooper has been going through a huge wave of frustration recently

He was sidelined for 9 days, which frustrated him greatly, considering how much worse he has felt in other parts of his life.

He spoke his mind about the process he went through to get back to his team.

The 54-year-old was really frustrated!

"To be honest, it was extremely frustrating. I had to sit out for 8-9 days and yet I felt pretty bad at many points in my life. I think if you ask the players, most, if not all, of them will tell you the same thing."

The Canadian head coach may not be thrilled with his recent times, certainly his team is doing well recently. The Lightning currently sit atop the NHL's power rankings with 46 points.
