Greetings!
I'd be happy to help! First off, your thesis is a run-on sentence. The first sentence should end at "level." Let's see if we can make it a little tighter: "Both athletics and academics at the high school level are suffering as students continually see news of their sports heroes' use of performance-enhancing drugs." You would then go on to explain the connection. There are many ways you could write the thesis; just remember to keep it succinct and to the point.
I hope this helps!
