The conclusions follows: 1) The sorting of CSL team's offensive and defensive ability show the characteristics of the performance of the game is consistent with of rankings,The TOPSIS evaluation can reflect the offensive ability,offensive and defensive ability of each team better, and basically reflect the defensive ability of each team. 2) RSR method to CSL teams for a reasonable sub-file. 2017 season is divided into 3 stalls. It creat to combine the TOPSIS and the RSR ,quantifing the rationality of the 2017CSL attack and defense index capability and the division of the stalls, which can provide valuable reference for the future scientific analysis of CSL.

Key words: 2017 season, CSL, Offensive and Defensive ability, Sort, Stall division
