PSU.com provides a visual comparison of Madden NFL 08 vs 09. The screenshots show improvements in everything from character models to weather effects and stadium shadows.
Check out more comparison shots at the source.

To begin, notice that faces have been enhanced to fit NFL counterparts better, as well as jersey and arm muscles have been modified to look more realistic. Improved stadium and player self-shadow casting has been added, in addition to better field effects such as fuller precipitation, footprints in the snow, and better looking field grass.

Other improvements that would need to be seen in motion include more animations, now in 60fps for PS3, and better camera presentation.
