[MCU/GOTG] (Spoilers) At the end when Starlord has the infinity gem and they all clasp hands to fight it off, why was tiny little Rocket enough?

Drax, who is huge and the penultimate clasper, started cracking all the way to his fingertips. But when Rocket joined, everything became fine. Why?

And no, Groot was not part of this. Although Rocket was seen earlier holding a twig of Groot, if you watch closely he's not holding anything in his free hand in this scene. So it's just Rocket that manages to finally help establish control over the infinity gem. Why, when Drax & co was close to completely cracking?

To put it simply, Rocket joining in was the tipping point between them all being overwhelmed and the energy being sufficiently distributed for them to survive it. Think the straw that broke the camel's back. 

Hope someone more awake comes and explains this, because that was terrible, sorry.
