I think, BD & IND has improved lot - which indicates the lack of interest for the game in other major cricket playing nations.
This game is learned, developed based on First Class cricket - uncapped 4 innings game, which needs 350-400 overs at least to develop, or minimum 4 days. Sadly, we can't expect people following Dhaka Metro playing Chittagong Region for a game of 4 days these days, when they can enjoy Dhaka Dynamites playing Chittagong Vikings in 4 hours.
It's a sad but reality for cricket - slow, painful death. We might still see a game using Cricket bat and hard leather balls, but the fundamental skills of the game is diminishing fast, which is resulting into more one sided games, too many clean sweeps and venue dependent dominance by every team. This happens, when the fundamental skills of the game can't counter the natural hazards of the game.
Something brilliantly explained by Nick Faldo (Or Collin Monty??) in recent Ryder Cup. USA came with 12 Golfers, 8 of them in Top 12 of World Ranking, while Europe had just 3 in top 12, and half of their 12 players were outside top 50 in PGA ranking. Yet, on that very special Paris Course, USA was comprehensively beaten in every contest, apart from 1st Days' 1st doubles games. That National Golf Course is just ~6,500 metres designed for per 72- very narrow curvy fairways, deep/stiff bunkers, extremely risky water hazards and pin positioned at the edge of green, surrounded by bunkers and water hazards. This is a very traditional European course which needs extreme precision, skillful chips and well measured putting, even for a per 4 of 300 metres.
US Courses are changing into totally different directions - average length is close to 7500 metres, often spread out & flat, where power driving US golfers can score far better on per 4 & per 5 holes. An average tee shot in US PGA is around 350 metres these days, which means most US golfers could have reached green on per 4 holes at Paris from their tee shot - they tried, and ended in sands or water. Patrick Reed one day shot like 85 (or 86), very next day 66 - he didn't change his game and kept hitting hard - on Day 3 most of his hard hits landed where he wanted and he had like 8 birdies, first 2 days he needed one boggy for almost every per 4 holes. Jordan Speith had totally opposite - hit 69 on Day 1, 81 in singles later.
Cricket is becoming something like this - players playing on same tempo without bothering to adjust their game for the condition or diversity - the day it clicks, it's 383, next day bowlers might click and it's 151.....
