It's like tricky question. If you can not take the rebound, you can not have a chance to make a FG plus you gotta be on the defensive side again and again. But even though you get the rebound but can not the make a FG, it becomes just an unsuccesfull effort that's why you gotta regard all the facts and stats in basketball while analysing. Pace of the game, not the numbers but percantage of the rebounding, distribution of FG (3 point shots, transition offense, put backs etc) all that matters and change the scenario.
