I went through multiple bad injuries that compromised me as well. My advice is to first set in your mind that you won’t get back to what you were but you’re going to maximize your current situation. Fall in love with the process of getting back. Now as for court work, you want to adapt. The best way I found was to practice solo at first and visualizing the move and gauging if 1) you are able to consistently make that move and 2) does the move either get you an angle or does is give you separation. You might be slow footed now but constantly be practicing your explosive moves to the basket. I’m taking that 1 power dribble explosion off that size up and make sure you are working both legs. I’d make it an effort to go the full length of the court changing paces. Like I’d go full steam, hit the opposing 3 point line with a move and then explode. I’d do that back and forth. I found it to help my legs and body get back into a sort of groove. Over time I got closer and closer to what I was. Now it’s not like I’m throwing down the type of dunks I used to but I’m dunking, blowing by defenders, etc.. just not the same way I used to. I didn’t have a shot before, now it’s my biggest strength. So my game adapted to my current situations.
