There are so many more factors though, all I'm saying.
Von Miller arm length/wingspan for example is below average for his position and he may be one of the most insane edge rushers we've ever seen in their prime because of all the other intangibles.
A lot of people missed on some really good prospects because they were focused on the measuring tape too much. Bruce Irvin is another one.
Of course more goes into it. However for those positions wingspan has ALWAYS been a
Every situation in the world has its share of outliers and anomalies. Mentioning 2 guys at that position doesn't erase the myriad guys who couldn't cut it due to just not being built properly for the demands of the position. Ereck Flowers is a great example of this: drafted number 9 overall at LT. An OT drafted 9 overall is supposed to be a cornerstone guy for at least a decade for you. However due to his short arms he just couldn't cut it as an OT, got moved to OG and now can actually continue playing in the league because his wingspan is more suited for Guard than at Tackle. His career would be over if he stayed on the outside.
Lastly, if you grade out 2 guys at those positions and they grade out fairly similarly, you'd be an idiot not to draft the guy with the longer wingspan. Not saying it's the only factor at certain positions, but yes it's a very critical factor at those positions.
