Why does my goalie and defense suck in NHL10 online league?

Whenever me and my friend play with our league it seems like our goalie couldn't stop a beach ball. Not even one timers or close deak shots just outside un-screened un-deflected shots go right by him when we are working our butts off to get it in the zone and get good shots that never work. Often we outshoot the other team and get much better opportunities but still lose. Also it seems like our computer defense cannot do a thing it ends up with our wings playing the defense. They never step up or do anything they always go for lift and poke checks and never land them when the other teams defense are superstars stopping us on nearly every drive. They block shots, lift ans poke check us and get the puck loose, and step up and lay us out i dont get it it seems like the other teams goalie and defense are superstars and ours suck.
