This is an older article but a good one where ProFootballTalk breaks down Mitch Leidner. TLDR...he's not a first round pick, but he may be draftable with a could improvements.
First, here's what stands out.
The first thing that stands out is you have the size, you have the look like I said. There are actually a lot of things to like on tape. He had a high percentage of what we call "big-time throws," which is simply our higher-graded throws because we’re grading every single player on every play. Our higher-graded throws are downfield throws, extremely accurate, into tighter coverage, and (Leidner) actually had a really high percentage of those.
