I pretty much agree on this. I haven't played 10 either on the Wii, but I liked the allplay controls in 09 better than what they have now. Now it's all waggling the wiimote up and down or pressing buttons - I really liked the feature to twist the nunchuck to juke etc. In the attempt to make it more accessible they didn't go all the way either, for example there is no autosprint, so there are still 5 buttons for running moves. Passing by pointing the wiimote at the receiver is new and fun, but that's all that's to it.
The only reason why I would play it again is to get someone new to Madden in the game (via 5on5, which also works in road to the superbowl and the "betting" mode). If you have a PS3 or XBOX there really is no (big) reason to buy the wii version imo. I'd rather get Madden Arcade for 5on5.
