I was just implicating that the Chargers deep pass attack tends to make the throws look more exciting because Jackson and Floyd use their height and jumping to make catches over defensive backs. Meanwhile, the Texans deep pass attack tends to make things look a tad bit easier because, while Andre Johnson could be making those catches like Jackson and Floyd do, he has the speed to create real space.
Both quarterback benefit hugely from the size of their targets, but Schaub doesn't have to throw as many balls near defensive backs because he can lead Johnson so much. I wasn't trying to knock either offensive system. In fact, I love what the Chargers have done from a conceptual standpoint (which is hard for me to admit).
