Someone being a great crosser with his team doesn't translate to the same for England, in so much as you only have to have watched the game to see there wasn't great delivery. The reason why, firstly Baines had little support down the left, second particularly in the first game Rooney refused point blank to play left wing. There were few to no overlapping runs, few brilliant crosses and mostly there were very few blisteringly fast counter attacks for strikers to get on the end of.
He did categorically not get good service in these two games, and he particularly in against Uruguay started dropping deeper later in the game, mostly in the second half, and in doing so created a goal.
Two goals being made by crosses doesn't equate to loads of good crossing all game long, and the second goal only got made by a cross because of Sturridge's work when he dropped wide and deep.
Sturridge wasn't dropping that deep early on and almost certainly if his instructions were to do so he'd have done so from the start. A striker dropping deeper and deeper to get on the ball during a game without any quality service is very very common. The difference with Rooney is, he drops deep early looking for the ball, he doesn't make good runs to make space or look for the passes so no one can pick him out and when he does drop deep he rarely creates anything. Rooney dropped to the half way line literally dozens of times and did nothing of note. Sturridge did it a handful of times and created a goal. He dropped deep on the right wing, got the ball, turned a few players and instantly looked to pass forwards and in doing so made the goal.
Rooney drops deep, gets in space, gets the ball, and refuses to drive forward, rarely passes forward dangerously and on multiple occasions like the one Sturridge was in would have run backwards and passed to a defender rather than take on a few players and find the ball forward.
Size doesn't mean anything in leading the line, not least because Sturridge is tall, he just doesn't look it, and has plenty of pace.
It's the difference between a slow ass build up and a cross into a filled box when the striker has made his run and then has to stop, and a fast attack in which the cross can get between the defence/keeper and a striker can continue running on to the ball. There were LOADS of crosses like the former, and very very few like the latter, two of the latter resulted in goals. The former only happened when Rooney.... wait for it, ran beyond the defence, drove forward with pace and played as an actual left winger. When he didn't run at the defence, we had no space, no outlet to work in.
When your midfield/offence is slow because the guys in the middle slow down every attack, you end up needing to attack like Barca at their best, facing a solid and set defensive line. When you attack with pace, you face a broken defensive line that is retreating and will leave many more gaps.
Look at the England goals, poor defending, but it was players retreating, the back line turning in to 4 disjointed players. When the key men in the middle, in this case Gerrard and Rooney(others VERY guilty of it too) slow down every attack half the battle is lost.
