Players are doing more of everything this year... More lifting, more drills, more 11x11. Harman's article is only talking about one part of it (As a given rule.. Most of his articles are based in truth, with a lot of misinformation)

Players spent the time between spring and fall doing more PRP's (Player Run Practices) than before... Those months of 'drills' have allowed them to spend the first part of the fall learning the new office.
