Really? With Markov playing 20+ minutes, PK would not play 24 mins a game. My guess is PK would be around 18-20 mins, which depending on the game would go to 22 or so.
How much did he play the few games they were together? Too lazy to check right now.
Last year, the two times Markov played over 20min (21-22min), PK played 27 and 28min. However Markov was coming back from injuries.
The season before, PK was a rookie, and Markov only played early in the year. So it's only normal for PK to be broken in and not given big minutes early.
All in all, there's no way to know. PK would likely lose a little time, maybe a minute or two here or there, but not that much. It's not like he struggled with the heavy load.
Other guys like Hammer and Spacek did though. And guys like Gill should never play 20min, just like this year, no way Bouillon would play 20min+ with PK in the line up.
