Did Sager know more about NBA compared to Murray Walker knowledge about Formula One? I have not seen many NBA games - however most of the time the sideline reporters seem to never ask tough questions; most of the questions seem kind of ... silly or elementary school grade. A la has he ever asked from player A why he did a flagrant foul on player B etc.
At least in the soccer, F1 or winter sports commentators never say samething like "wow, Lindsay Vonn got the best time on downhill - another 50 USD contributed by this or that company". Or "WR by Usain Bolt - brought to you by this or that company".
