what makes rugga guys so special

I've just played rugga rebels members you can check out my schedule if you wish I'm in TIR the international ruckers and I thought it'd be an even game cos I know there guys have knowledge that I clearly don't but how is it possible that level 59 and 62 are faster than a guy at 68 what makes me even more confused is how they can generate so much speed yet when I check there player settings most of them are using only half on attack and defesnse speeds in the player settings?

can anyone explain what is going on why are they handsdown better than me, and why they're so significantly faster than that of my team? not saying they're cheating like but it does appear odd when you look at some of there players and how they're so lowly ranked yet they're somehow winning league with over 500GA are some of them.
