Which has almost nothing to do with the medical team.
Lisandro returned twice given green light and end up with same injury, which means the medical and rehab team didn't do their job.
I am sure it happened with Shaw and Mount too who both had many delays and shite recoveries getting injured again, and couple of other players who prolonged their injuries and if I am not mistaken some players had to take same operations twice.
Also if the players are getting same injuries you don't think medical team should suggest our coaches that something is wrong?
