Madden NFL 25 X-Factor Players

The question I have is what does a NFL player need to do to have a Superstar/X-Factor ability in Madden NFL 25? The reason I ask is because I always thought it was attribute stats; like having a 90+ juke and spin attributes in order to have the “Evasive” ability which gives them better juke and spin moves. I looked at Jonathan Taylor (starting RB for the Colts), and he has an 91 Stiff Arm attribute and was given “Arm Bar” for more powerful stiff arm animations. But, turn around and look at Najee Harris (starting RB for Steelers) who also has a 91 Stiff Arm attribute but no “Arm Bar” ability. Honestly, it really seems like only NFL players who have a big name in the NFL that everyone pays attention to gets abilities rather than the players that actually hold high attribute stats for those abilities in the game. This has been an issue since Madden 20 when abilities were introduced. Highly big named players will get abilities in madden but not players that actually hold high attribute stats for those abilities. Do you (EA) do this on purpose because you all only care about the the big name players?
