Chris Gayle ended up as the leading run-scorer in the round-robin stages of the IPL by a long way - his tally of 733 was 164 runs more than that of Shikhar Dhawan, who was second with 569. In all, Gayle scored 31% of his team's total bat runs during the tournament - Royal Challengers Bangalore scored the second-highest number of runs in their league games, with 2351. Gayle's stats in wins was especially awesome: his scores in the seven matches that Royal Challengers won were 81, 87, 4, 26, 82*, 57 and 128* - 465 runs at an average of 93, and a strike rate of 162.58. In defeats, he scored 268 runs in seven innings at an average of 38.28 and a strike rate of 157.64, which are pretty exceptional numbers by themselves. Gayle has also struck 59 of his team's 117 sixes, which is marginally more than 50%. Thanks largely to Gayle, Royal Challengers also struck 30 sixes more than next-best side - Delhi Daredevils are second on the sixes list with 87.
Apart from Royal Challengers, the others teams that relied on one player on a large chunk of their runs were Kolkata Knight Riders and Deccan Chargers. Gautam Gambir contributed more than 27% of Knight Riders' runs, with Jacques Kallis, the second-highest run-getter for them, managing only 15%. Shikhar Dhawan's percentage contribution for Chargers was 25.84%, but Cameron White contributed mightily for them too, scoring 479 runs, almost 22% of their team's runs. The team with the most runs in the round-robin stages was Rajasthan Royals: they scored 2393, with Ajinkya Rahane, their top run-getter, contributing 560 of those - a percentage of 23.40.
On the other hand, there were four teams in which the leading scorer contributed less than 20% of the team's bat runs. At the bottom of the list is Pune Warriors - Robin Uthappa had a below-par tournament, but he was still their leading run-scorer, contributing 18.55% of their runs. Steven Smith had better numbers (average 40.22, strike rate 135.58), but didn't have as many opportunities to score as he was batting down the order.
