Did I sayb they came out the same year??? RIF
You said Lebron and Melo were 1/1a coming out of high school. So you were saying they were 1 OR 1a in each respective year that they came out of high school, but in different years? If that's what you meant, it's certainly not what you said. Saying someone and someone else are 1/1a means that they are 1/1a at the same time. Otherwise the slash is improper in the sentence. (See, e.g. when people say Revis and Asomugha are 1/1a in CB rankings - they are saying they are 1/1a together, not separately). If you wanted to say they were 1 OR 1a in the years they respectively came out, that's different. But you didn't say that. You said something else.
Still not sure how it's relevant though.
You can just admit you made a mistake. It's no big deal.
