Goku and vegeta goes ssj blue 2

Everyone is just talking about Vegeta but have anyone noticed Goku is actually dodging and stopping jiren attacks though he wasn't able to dodge or attack earlier as ssb kaioken ..
Something must have changed this time for both Goku and Vegeta..

I think they attained the ascended version of super saiyan blue and and they both tranform theirself into ssj blue 2 forms . As we can see this hair similarity of ssj 2 and ssj blue 2
Thats the main reason of jiren struggle against both Goku and vegeta .

I think vegeta is also attained this because he is also doing well against jiren

vegeta is doing better then hit and goku's first fight agains jiren 

Compare to previous fight of goku vs jiren
Goku also found himself easy . In the preview we can see that goku easily defend the jiren's punches with smiles and much ease.

Other case we can say that the jiren is hiding back and want to surprise both vegeta and goku but in my opinnion this not gonna be happen,

Goku and vegeta improved so dramatically as we know saiyans are very good learners and improvers. They improve after every fight
So i hope they goes ssj blue 2 in next episode and this will makes things easy for them. But keep in mind even UI could not defeat jiren
So ssj blue 2 will not enough for beat jiren .

They have to put much more efforts then this.
