Sorry but I'll call the analysis results rubbish. Full marks for trying though... but I think the logic is flawed.
Lets first get one thing straight... are we talking the pace attack you would have for a match or just your bench strength?
For pace attack, what you should do is stick to maybe 2 (3max) pacers at a time and take their average... which would give you a 7 out of 10 for the current team, and a much higher one for other eras.
If you are talking your strength sitting on the bench, you still cant put in more 7out of 10s and rate them better than three 9 out of 10s and a 6 out of 10.
When you're playing a match, currently you'll just have one or two mediocre 7/10 rickshaws playing for pakistan and their combined affect is just that... a lame 7/10 at best.. nothing more (probably a 6/10 for having no brutal pressure right at the start that a 9.5 would put).
And you're rating Aqib a 6.5 and Sohail Kukri Tanvir a 7? Give me a break... the guy was an 8 atleast... he always had the W's around who were better so we never saw how devastating he could be... If you bring an Aqib in prime in todays team... he might be touching 8.5. He was too good to be a 6.5, we just never got to appreciate him thanks to the W's.
Looking at your analysis, looks like we have nothing to worry about! We are doing just as fine as the W's era. Are we??
