Maybe, you tend to not have the hip flexibility and speed and agility while going backwards at that hight.[/QUOTE
You're absolutely right. It would be guys who are kind of "freaks of nature" by today's standards, but it will eventually happen. I look back to when WRs weren't all that tall. There have been about 40 guys @ 6-1 or more that have made the grade over the years, and only Harold Charmichael was 6-8. Most were 6-0 or under, because they said bigger guys couldn't make the cuts, and weren't quick enough in initial acceleration. Of those 40, I'd say about half of them have come along over the last 20 years.
There have only been about 35 CBs over 6-0 tall. But, we're seeing increased height in WRs at college level, which is going to force colleges to convert those taller WRs with bad hands into CBs, if possible.
The ever changing face of football. I remember when they thought a defensive line, or offensive line, that weighed an average of 250# was about right. Now it's 50 to 70# more. Guys are huge!
