Vikings Vice President of Player Personnel Rick Spielman sees a different reason why Heisman winners can be such a hit or miss prospect at the NFL level.
"There are guys that can have successful collegiate careers but because they're lacking in some type of physical trait, it doesn't equate up here with bigger, faster and better athletes," Spielman explained. "Some of it has to do with the type of scheme they played in during their college career. Their production numbers are way up because they're featured in an offense that fits them. There are a lot of schemes that you see at the college level that you don't see here in the NFL."
