Sorry mate, that is making it way too subjective, like: "When he made that century, how fast was he running between the stumps?"
There is also another point here. A team like Bangladesh doesn't need someone to bowl them quality bowls for them to get out. If they did, they'd surely be a better cricket team. That is the point, whilst they may play well occaisionally, the majority of the time they're not good enough to bring in the quality of wickets argument. I know this is an argument for Murali really, but this reasoning is not consistant or measurable. It's taking the argument and digressing just for the sake of saving face.
What about balls that are bowled but were really good yet dealt with suberbly. I'm sure Murali wasn't bowling crap to Lara even though getting smacked around. What about those "great bowls" that didn't get a wicket. It's about what you get and what you don't get, and who you're getting. The bowler is not the only variable in getting wickets, there are people called batsmen
. Unless Rafique or any of the Bangladeshi's really improve in their batting, this kind of assessment is pretty flattering. EVEN so, where would you rank the Bangladeshi's? Last surely? So, as stated, bottom of the pile.
