He is not going to be picked in the IPL from now on either. He is past his prime and was a liability for RCB last season. It is a shame that PSL didn't exist during his prime years.
A poor title though. It gives the impression that Gayle is good enough for the IPL but not good enough for the PSL, which is a pointless, jingoistic statement devoid of any ground realities.
The standard and the pool of players in the IPL is 10x better than the PSL, and any player who is good enough for the IPL is obviously going to be good enough for the PSL. However, the reverse is not true. There are plenty of players in the PSL who are not going to get picked for the IPL.
This perception that IPL is so much better than other leagues, is as lopsided as you are claiming the OP is when comparing today's Gayle with 10 years younger one... The real attraction for these leagues, specially IPL is money for players, in that regard IPL is obviously better, but lets be clear, its not an NBA of Cricket, far from it...
All these leagues have inferior quality even in T20 compare to international cricket. T20 itself is Mcdonald of Cricket, popular in numbers but junk in quality. The only reason, I care about PSL is that we can unearth fast bowlers, who otherwise will not get a chance at national stage and maybe Tulas like Fakhir, those guys are needed in national LOI team...
Quality of international players is not so much different in IPL, last year Ben Strokes was highest paid international player, he is a good allrounder, but non of his skills are exceptional. He is no Sobers, IK or Kallis, far from it...Last year Strac did not play IPL either, best bowler in the world. They have AB and Warner, but that's about it...AB, Kohli, Gayle with all their powerous have yet to win IPL in 10 tries...In IPL guys like Maxwell and Gayle shine who are found out pretty quickly at international level...
I am not so sure local batting quality is huge either, most of the power positions in IPL are outsourced to WI/SA/AUS/NZ players, how many power hitters India has produced in last 10 years? - Rohit Sharma is still their biggest six hitter, which has nothing to do with IPL...We thought one thing these leagues are going to produce are power hitters, so far we have not seen great supply from any league, despite extra ordinary amount of money... In AUS things are going worse, they are producing horrible batsmen in last few years, all signs are this trend will continue...
If IPL grows in future it will follow model of American sports, where sports follow the talent and not necessary feed teams based on majority race. When American sports are opened to African American, landscape changed dramatically, within 3/4 decades, even in base ball Latin America is quite dominating... If IPL wants to be the best show in the town, they need to diversify both format(go beyond T20, fast food has little shelf life) and recruit players from other countries like Yankees, who go to hostile countries like Cuba(best pitchers still come from Cuba) and Venezuela to get the best talent not to mention the gettos of big cities, to get sharp kids...
India as a team is better than us, that is still debatable upon which format and condition we are talking about...Despite having so much money spend, playing top teams all the time, they are still marginally better than their past, they still have one really good batsman(which they had 20 years ago as well),they still struggles to produce high quality fast bowlers, they find it hard to win abroad, locally they win by spin which they have been doing since 70s, they have not added any dimension to their game yet, they are no where near WIs of 80s or AUSes of 2000s, who dominated the world, again far from it...
