Which CS2 Pros Perform Better (or Worse) Against Top Teams?

Recently I’ve seen lots of discourse about degster, broky, and others performances against top teams. I wanted to research how players performed against different tiers of ranked teams to see if some narratives were justified.

The first thing I did was collect data. I decided to use data from CS2 matches only (~20 months) to get a big enough sample for each player. I also only included players with at least 20 maps against the 4 different groups I collected data for. The 4 groups are:
Opponents ranked #1 to #5 (Henceforth referred to as Tier 1)

Opponents ranked #6 to #10 (Tier 2)

Opponents ranked #11 to #20 (Tier 3)

Opponents ranked #21 to #50 (Tier 4)

This resulted in 90 players that matched the criteria. For each of the 90 players I calculated:

-The difference between the combinations of tiers (Ex: Tier 2 rating minus Tier 1 rating).

-The standard deviation for the players rating across the 4 groups.

-The slope of the players rating across the 4 groups.   

Here are some of the notable results:

-ultimate has the highest standard deviation and by far the biggest falloff from tier 3 to tier 1. 

-Krimbo has the biggest falloff between Tier 1 and Tier 2 (0.83 to 1.07).

-jL may be the best “big game” player. His rating against Tier 1 is higher than his Tier 2 and Tier 3.

-The biggest Tier 4 and Tier 1 difference was a tie between Krimbo (0.83 to 1.10) and donk (1.26 to 1.53).

-YEKINDAR’s Tier 3 rating is 0.12 higher than his Tier 4 rating (41 maps in both tiers).

-As to be expected, nearly everyone has a positive slope (rating tends to go up against easier competition).

-JT has a 0.94 against all 4 tiers with at least 50 maps in each tier.

-floppy is the only player with a negative slope. His best rating is against tier 2.

-degster lives up to his narrative. He has the 4th lowest slope. He has a higher rating in Tier 1 and Tier 2 than Tier 3.

-NiKo, despite recent criticism, is extremely consistent. He has the 3rd lowest slope and 2nd lowest standard deviation.

Here are the 10 players with the lowest slopes (rating similar against all tiers)
