The amount of information in books I've read that has flowed in & out of my pretty little head without sticking even for a moment is probably stupefying, but something I've always remembered from a Lou Holtz book I read my freshman year of college
(which was in 1990; I’m sure they started printing copies of the book as the clock was ticking down in the West Virginia game) is that while someone’s foot speed may too slow to play tight end, it can be faster than most offensive lineman, therein turning a seeming liability into an asset with a quick position switch. This has popped into my head over the years as a professional creative with a surprisingly high level of effectiveness. His 1988 national title is my favorite college football team of all time - and that's probably not changing anytime soon since I watch about 4 minutes of college football every decade now - and while that team, had a million star players
(including my favorite, Michael Stonebreaker) there was no question who was the biggest star, and why that star was the one & only Lou Holtz.
