Nottinghamshire batting order

Interesting that Nottinghamshire bat Swann (County average of 26) ahead of Broad (Test average 29), and Ealham (County average of 31) behind both of them. I would suggest that Swann is the weakest batsman of the three?

It doesn't seem to matter much as they racked up over 500, with Chris Read who seems too weak a batsman to bat at 7 for England, scoring 125 from number 6, higher than all 3 of those mentioned above.
