Being a good athlete doesn't make one a good football player. Russell = bad football player. Tom Brady = HOF football player. CJ Beathard = NFL caliber football player. Lanning = not draftable
Now wait. Randy Pete has told us that the scouts will find Lanning and will know who he is.
Note: I don't think it's crazy that Lanning could play in the NFL as a linebacker, given his size/speed combination. But no one has any idea yet as to how well he can play linebacker.
