It just hit me that Vegeta did precisely what Whis advised he should start doing way back during the resurrection of f arc in the lead up to the tournament of power, stating that the reason he's always one step behind Goku is due to the fact that he's always walking around with a chip on his shoulder, and that he needs to relax and take some time to just rest and live a more normal life kind of like Goku does every now and then.
Vegeta was playing more of a relaxed family man role, clearly enjoying life and not obsessing over Training every single second. As a direct result I think Vegeta will be all the better and more powerful for it, and it's why I strongly suspect that Vegeta may very well have something big up his sleeves in this tournament also.
Can you guys imagine that at a key stage of this tournament, possibly towards the end part, not one, not two, but all three major saiyan warriors on the universe 7 side tap into far greater power, sending a clear warning shot to all other universes as to just how monstrous universe 7 really is. Then the tournament ends not with a clear winner, but with what fans will consider an implied winner based on what we all just witnessed from Vegeta, Gohan and Goku.
