I will add to my last statement, injuries do not get enough credit for how well a player does way too much of the time. When a guy struggles it is almost always the fault of the player on here but how an injury affects someone and what the recovery process is like play a huge part in how guys that have to be operating on all 8 cylinders to play well perform. Things like Krejci over the last two years he was playing arguably the best he ever had at the start of the 15 season, his unoperated hip started bothering him and slowed him down, he had surgery and didn't get to train at all in the offseason and struggles for most of the year and it has to be because of his age.
