Undrafted in life

The NBA Finals featured two undrafted, unlikely standouts in Alex Caruso and Duncan Robinson. Anthony Davis is No. 1 on ESPN’s list of top free agents, but Davis leaving the Lakers is about as likely as LeBron James retiring to open a taco stand. The more surprising players were the ones who might actually change teams: VanVleet at No. 2 and Detroit Pistons forward Christian Wood at No. 3. They, too, were undrafted.
“I carry that with me every day,” VanVleet said.

I feel this. I don't think you can quantify how important that chip on your shoulder is later on. There's no better motivation.
