No I'm describing ceiling. Your ceiling is the best you can be, and if your arm strength is below average there is a limit to how good you can be. Floor for basically all draft picks is "can't play in the NFL" and while really terrible arm strength might matter there, it does less than it does what your ceiling is.His 40 was averageish, as you say. His 3-cone and shuttle were also pretty much average. But having average speed and agility at 6'3" 228 pounds is really impressive. He has an 8.45 RAS. But if you don't consider size part of the physical traits, fine: what I'm really objecting to is characterizing him as polished. He wasn't and isn't, and obviously he wasn't a high-floor guy by any stretch of the imagination.
What you're describing is floor, not ceiling. I agree some guys lack the requisite arm strength to be starting NFL QBs, but that just means guys with questionable arms have low floors. For guys with adequate arm strength, I don't think it has much impact on ceiling. Drew Brees had a top-10 all-time career with an arm that was no better than average and often worse. Denver Peyton Manning had a terrible arm and was still very effective until his last season.
I'm fine with calling Harry unpolished, though I thought I remember his polish being a selling point at draft time....
looking at that RAS, you'd see that his size and bench are driving that score, his splits are well below average as is his 3 cone, Shuttle is on the lower end of average..
That's a mediocre athlete.
Edit- looked up some pre-draft writeups.. mixed opinions on his polish, almost all agreed he was an uninspiring athlete other than his size/strength.
