Interesting point about Dowrich but the majority of the reason for the average of 40 is his batting at 6 significantly bringing things up. At 7 he averages 32, and the one innings of substance in that time (which brings that average up from the low 20s) came under a distinct lack of pressure bearing in mind the match situation when he came in.
Amongst people with a reasonable number of innings at 7, he’s behind de Kock, Pant, Sarfraz Ahmed and Paine and not much ahead of de Grandhomme, Pandya, Buttler and Dickwella which probably gives an indication as to why people wouldn’t immediately think of him when discussing the team’s top batsmen?
Fair point, I was using his overall average over the time period but point taken his contributions looking more closely seem to be more impressive at number 6 then number 7. But even so I'd argue most would put Dickwella and definetly Buttler far above Dowrich in a ranking of Test batsman. But my presumption that he probably did better than the majority of his contemporaries at 7 was overstretching I can see.
But I do still think he should be in the discussion for the team's top batsman. His hundred v England at 7 came with West Indies 61/5, effectively 273/5 a dominant position but I'd argue given England had got 5 wickets for 9 runs to reduce West Indies from 52/0 to 61/5 had West Indies got bowled out for say 100/120 England might have fancied a good crack at a 4th innings chase. Additionally, his overall record since the start of 2018 - average 40 is bettered by only by Jason Holder who's highest score came in the same innings and at a time when Hetmyer and Dowrich had alieviated the threat of total collapse. Aside from Holder and Dowrich only 3 other West Indian batsman average over 30 in that timespan. Blackwood (38 average from 1 innings), Brooks (34.8 average from 5 innings) and Hetmyer (31 average from 20 innings).
Other notable West Indies batsman over that time spell
Campbell (29.80 average from 12 innings)
Chase (24.23 average from 27 innnings)
Brathwaite (21.33 average from 29 innings)
Hope (20.08 average from 26 innings)
Brathwaite and Campbell do have to front up against the new ball which will hurt their average. Hope has played quite a few innings at 3 too although averages worse then the 2 openers too but over the last couple years its hard to argue they've been better then Dowrich in the Test format - Brathwaite and Chase have at least had somewhat decent if unspectacular Test careers to support their argument not so much for Hope. Who would you say the West Indies best Test batsman is out of interest?
