I'm just he's a heavy lean because the National Recruiting Analyst for Rivals considers he's a heavy lean
for Michigan and so does
the Mid Atlantic Recruiting Analyst who covers Peppers' region and school closer than most. Peppers was really hot on Stanford this past fall and when he made his top 5. Based on these two reliable writers and the fact that he has been hot on Michigan this past month, saying his visit there exceeded his expectations which were already high and that it was his best visit, while he has been relatively quiet regarding Stanford recently is why I would call him a Michigan lead.
