Jordan 3 Heel Drag

I found a good prices pair of slightly used Air Jordan Crimson 3s online. The condition is marked 8/10 because of minor creasing and heel drag. In the pictures thView media item 1591657e heel drag doesn't look that bad in my opinion but I don't know if that's a factor that could over time pop or deflate the air bubble. Should I buy these? And how bad does the heel drag look?
