It's possible to have success in 4.6 but it means grinding out long drives and running the ball a ton and not using any long passes or any passes that aren't quick hitters because sacks are through the roof.
Hitting big plays (20+ yards) is nearly impossible unless someone breaks a tackle or two and old reliable FL Hitch is still a dominate play but not for long TDs, just 1st downs!
It's much more like football in the 60s and 70s when passing numbers were down and the game was centered on field position and running the ball.
There is nothing wrong with that if you like that brand of football...to me it's boring and QBs Stat lines of 210 yards passing is a big day in 4.6.
I'm 53 years old and have watched the NFL develop into a passing league where you need a big time QB to win! This game has taken a giant step backwards in my opinion because to throw for 300+ yards now means multiple sacks and interceptions added to ruin the effectiveness of any QB.
4.5 had its share of issues but custom rules helped stop exploits and you still had 10-0 games along with 53-46 games and big comebacks happened along with last second come from behind wins....4.6 doesn't allow for much of either....if you are down 4 points with 1:20 remaining you are screwed because you can't abandon the run if you plan on moving the ball because it takes 10+ play drives to score for the most part....one penalty or negative play for lose ends drives...period...end of story!
