Here is Matt DiBenedetto. You might not remember this, but he started as a JGR developmental driver in 2009 and 2010.
He was decent, but JGR got rid of him before he was even 20. He did eventually bounce back, but as of now, he doesn’t have a ride full time.
Out of sheer curiosity, I decided to compare the first 47 races (that's where Berry is as of today) of the past four drivers of the Wood Brothers 21:
