Your argument is fine if you don't care if every match finishes in less than 2 days and no seamers required.Somerset are playing three spinners and have got off to a cracking start. The pitch is taking spin already, and Middlesex have Rayner injured and not playing. Looks like Somerset have a massive advantage in the spin department, probably enough to ensure an easy win for them.
Patel, Stirling & Malan all bowled so far and both wickets to spinners!! If they are Middlesex`s only spin options, then I think Middlesex are doomed (hopefully with very few points).
I remember Hadlee & Rice demolishing county batsmen - it never seemed a "fair" contest to me with three-day matches often finishing in less than two days.
