With the greatest of respect, I think you've missed the point of the article.
I agree that Dublin were eaten alive. But you can be eaten alive for a multitude of different reasons. I could have told you at half time what the problem was, eyes on the line as you say, but the stats put evidence and quantifiability to it all.
For example, Tipp ate Kilkenny alive in last year's All-Ireland final, but could you tell me how? I could. Tipp won 28 high balls cleanly and lost eight!
If KIlkenny play Tipp this year, do they need to re-invent the wheel? Not by my reading. They need to get a half forward line than can compete with Tipp's half back line on high balls and all other factors are more or less even.
Unfortunately, by my reading, Dublin's problems are deeper. Though tactics can play a part, the side who can manoeuvre the most uncontested strikes are usually the technically superior side. This reading of 33 to 22 by the fortieth minutes strongly suggests that Dublin simply don't have the technical ability compared to Galway, who aren't exactly miles ahead of the pack.
I agree they were eaten alive. By my reading, that's why. Galway are better, illustrated by creating significantly more uncontested strikes.
