Why is this game so unrealistic with injuries?

[Pupack]

yeah, injury engine is terrible..i see more and more abandoned teams, more and more players leave after few seasons just because things like injuries... if nordeus wants only newbies and their money and they dont care if they will stay here more than 3 seasons... its sad. But its business.. nothing more, nothing less...i would like to spend more money if i will se some improvement or some feedback, but i cant see improvement..there is so many things that make you feel like its all so random.. even tha results...
