I'm going to go out on a limb and say there is no Russian in the US currently serving a 9 year sentence for weed so there was never going to be an equal trade.
We're also seeing fewer fakes from special teams and fewer onside kicks. Should also note that the Lions 3rd down conversion percentage is 8 points higher this year than last year. They are finding themselves in fewer 4th down situations. Dan Campbell is smarter than people give him credit for. He has all the meathead football speeches but he knows what he's doing.
The point is, Elway only once led the NFL in anything and that was passing yards. His MVP season of 1987 he didn't even finish in the top 10 of some categories. He's in because he played in 5 Super Bowls.
Because Stafford basically missed his first two seasons in the NFL. Stafford was at least at one point the all time leader in yards per game. Matt Ryan has played over 40 more game than Stafford and averages fewer yards per game than Stafford.
