@Mamoon Regarding the finisher gimmick, here are some samples:
1) 2009, West Indies: Dhoni promoted himself to No.3, needed to score 11 off the last over. Yusuf Pathan took a single off the first ball of the over, Dhoni smashed a SIX and finished the game, scoring 46* off 34 balls.
2) Adelaide, 2012 vs Australia -- 13 runs required off the last over. Dhoni smashed a 112-metre six and the rest was history.
3) ICC World Cup 2015, Zimbabwe scored 288 and India were 92/4 when Dhoni came to the crease. Dhoni scored 85* off a mere 76 deliveries, with 8 fours and 2 sixes.
4) Dhaka, 2007 -- Dhoni, elevated himself to the No.3 position again, ended up with 91* from 106 balls, after India were 144/5 at one stage chasing 251.
5) Tri-nation Series Finale, 2013 -- Dhoni finished off the match when India needed 15 runs of the last over with one wicket remaining, hitting a six and a four.
6) Lahore, 2006 -- Chasing 289, India were 12/2 at one stage and 190/5. Dhoni smashed 72* off 46 balls to win the match in the 48th over.
7) Karachi, 2006 -- Chasing 287, Dhoni scored 77* of 55 balls with 6 fours and 4 sixes, helping India win 4-1 in Pakistan
8) Vizag, 2005, Sri Lanka -- Chasing 298, Dhoni came in at 3 and hit 183*, the highest score by a wicketkeeper-batsman in ODI cricket to date, hitting 10 sixes.
9) Mumbai, 2011, World Cup Final -- Chasing 275, India were 114/3 when Dhoni promoted himself above Yuvraj Singh and you don't need me to tell you how
that went. 91* off 79 balls in the World Cup final, taking on Murali and effectively negating his threat.
But sure, let's dismiss all of that because DK had one good finish. It's like saying a single sparkler is more impressive than a full-blown fireworks display. Clearly, the OP has a lot more to learn about cricket than they're letting on.
