Yes there are some weird moments but the game feels a whole lot better to me.
There's positives and negatives to the physics engine. It feels better and can create for some amazing looking plays. However, sometimes there are some weird tackling that happens that can look worse than when Madden had canned animations.
Overall, I will gladly take the positives of the physics engine instead of going back to canned animation with tons of suction that may not have had that many cases of looking strange.
