I agree science has improved. I think in your case you are mistaken j medical for scientists when in reality they are charlatans
Well, seeing how they overlooked Chiesa's return, I wouldn't say anything is a given. Didn't he go to Germany with a meniscal problem afterwards, if I recall correctly.
Explosiveness however is not dependent on the ACL or the cartillage so it can be back at 100% with proper guidance and plenty of training. It's hard work so one must be willing but he's a young pro athlete so if done right, he should be back in shape. Often only at their full capabilities in the second season after the comeback 'tho.
Anyways, back on topic. Need Veiga to hit the ground running. We're getting more shaky by the minute.
