Online is always like that...this game has sold less than 40,000 copies apparently add that to the host being lag free while the guest gets huge lag and you get empty online. Ive played about 6 games online. Its not worth bothering IMO. The games are too long and people jut quit if theyre down.
To get better at passing, you have to try to read the defence. Try to pick a play e.g. shotgun, slot cross...where you have
a WR going across the middle and your TE cutting straight out into the flats.
Now, watch the line backers. watch if they blitz, fan out of stay put. If they blitz the outside the look for your TE, if they blitz the middle then hit the WR in the slot
If the MLBs stay put and the WR the OLBs take the flats then look to your WR on the outside, but you probably wont have time. Dont be afraid to hit the x button (or A button) and throw it away if you feel shut down. Throwing and praying does not work!
Also, at the start of the play keep an eye on the saftey and if he runs infield away from your WR at the snap then you might have a one on one situatuion with WR and CB which seem to favor you most of the time (you will still get picked by a good CB.)
Also, on third and long its better to play for field postion and get a good punt in than to chuck and pray and get picked. Dont expect to score on every drive.
TE on a post pattern is a good high percentage play.
I once threw 11 picks in 1 game and lost 50 nil. Now I consistantly throw for 100 yards a game. I am 10 and 2 in RTBB season 4 after finising season 3 15 wins and 16 losses.
