What we don't know is what the league, and systems will look like going forward.
Standard drop back "Pro" systems aren't as prevalent anymore in college, and you are getting more athletes at the position than regular throwers. All the way down to HS.
The 6-5 240 sling it 70 yard guys aren't really around as much as they used to be, we're getting a lot more 6-2/6-3 guys that can run and throw it good enough. Spread systems, etc also affect the way they need to throw, vs how they can get by thru the systems. Once you get to the NFL level, you gotta be pretty damn accurate, or you're gonna get shredded.
Manziel went wild in the SEC, and even with how "good" he looked yesterday, those were two heaves that somehow found targets. Outside that, he completed, what, six passes?
Those six passes? 62 yards.
Perfect example of what I'm getting at. Stats are shiny, but did he really play all that well? Is that the trend that will develop once these elites leave, and the game is such a wide open version of its former self with all the spread fields, and no contact, so you can be meh, and still get 200+ yards and 133.9 QB ratings, while completing really just 2 passes that had an impact on a 60 minute football game?
Iono. I know players always evolve, and the game does too, but I'm personally worried 3-4 years from now, what's coming down the pipe.
