Trust me, 2010 is ten times better than 09.
A few tips --
HB Blast, reversing which side of the center you run to, will get you consistent 1st downs. I usually net 12 yards or so. I've once played an entire game, running that play, just reversing the sides I run to. Opposing D never could stop it, and I won that game by like 30 on All Madden. Just to prove a point.
Fucking forget about running any play action. The D NEVER bites on play action in 09. Your QB will get sacked every time.
Out routes, when you're having trouble passing. Obviously, stay away from the double and triple covered receivers.
Screen passes are your friend. For that matter, ANY pass to someone out of the back field, always nets big yards. And they almost never defend the guys coming out of the back field.
The game is pretty realistic with Barber. He's not an every down back, yet somehow, Jason Garrett and Wade Philips haven't figured that out yet. You'll do far better with Jones, but like in real life, he's prone to injury, so be careful, and keep a third back on your franchise if you're going to keep Jones the starter.
