I think I'm fully correct!
How old is the article you read? Were they assuming GB would be in the top of the rounds?
If the draft were held on the current records, they would move from 19th in the 5th to 24th in the 3rd. Thats nearly 60 more players available to them just there. Then add in the comp picks at the ends of the 3rd and 4th rounds they will also leap frog (10 or so, give or take) and you get close to 70.
