Sure - but it still doesn't consider the fact that it's Wilfork running into a 170 lb HB with the way the HB can just throw him off. I'd like to see that contact in real life.
What I want from pro-tak is the ability to purposely work through contact. The other things I'd like to see go beyond better hitboxes into a true physics engine.
Collisions are a big part of football, of course, and of physics, but not everything and not as simple as Madden has always made it regardless of the overall engine.
The focus on contact also ignores the AFTER contact, i.e. engagements, constant "skirmishes" etc. To me, that is the big picture. As is momentum, weight, weight shifts, etc. That's just the physical part of the picture even then.
And the whole picture always starts with the line play - the last thing that seems to want to be touched...but one of the biggest places true physics/weight/power/leverage/acceleration come into play.
