I always check players foul stats before buying them I just can't stand foul prone players after my previous horrible experiences.
i don't really agree with him being injury prone that's really just bad luck
FACT
Aggressive players foul more. Aggressive players are fouled more. All injuries happen on fouls. Therefore aggressive players injure opponents more and get injured themselves more.
OPINION
I think that after the GE has determined that an injury event has happened there is a second randomisation. This is affected by the level of the doctor which reduces the severity of the injury. I think it is also affected by the hidden physicality/aggression attributes of the players involved which makes the injuries more severe. It makes sense but I cannot provide proof, however the fact that these aggressive guys are always injured and not just in game but often for weeks suggests this is true.
