dude,
if there has been anything that having several career-threatening injuries has taught me it is...
don't, and I repeat DON'T listen to anyone who tells you what you will not be able to accomplish.
Obviously take it slow and follow all the rehabilitation protocols, but as for people trying to put a ceiling on how much the injury will stop you...forget about what they say.
Maybe your jumping "ceiling" will be lowered a bit by the injury, it's possible. The point is moot though because nobody ever reaches their ceiling.
If you want it enough to put in the effort to rehab and then train following the injury, I guarantee that you will be better and more athletic than you were before.
There have been pro athletes who have torn their achilles and come back and performed just as they did before. You will too.
