Nikolai Kulemin scored 30 goals in the 2011 NHL season, only to drop to seven in the very next year. A lot of this is due to the fact that Kulemin's 17.3% shooting rate from a season ago just wasn't sustainable and was bound to drop. It took quite a tumble, falling well below normal levels and landing at 6.5% on the season.

Kulemin had 217:55 of powerplay time in 2011, but last year, that was reduced to 60:25.

What are the odds that over one summer, Nikolai Kulemin suddenly forgot how to pick a corner, or decided he wasn't going to go into dirty areas, or had resigned himself to take only long, fluttering shots from the half circle? Zero. This is a case of pucks hopping over sticks in good areas, or goalies playing his shots just a little more sharp than they had been throughout his career.
