Trolling or not, really does demonstrate one of the most frustrating habits of cricket analysis, which is this idea that the quality of the bowling, the nature of the wicket, the relative quality of the players etc are determined by outcomes. So if Steyn, Philander and Morkel bowl and all average 20 and dominate a series, they are great seamers in conditions conducive to their succeeding, and if they don't return great figures, the opposite is true therefore runs scored are devalued. If a team makes 500, batting conditions are good so achievements are less important, but if a team makes 200 all out and someone makes 100 in that innings, it's automatically a better performance in more difficult conditions. It's just more complicated than that, and the only way to properly understand the conditions of a game is to watch it. The nature of a sport so influenced by weather, pitch, fatigue etc.
