Plum is quite good, both Cal and Stanford wanted her badly but for various reasons ended up at UW. She's very strong, though average height (5'8") and athleticism. But she gets it done.
Not not a carbon copy, I can see some Lindsay Whalen in Plum. Whalen may be more athletic, more magical off the bounce, more of a proper PG, better passer. Plum more of a scoring PG/2G, and more of a 3-pt threat (though oddly, Whalen was an adequate 3-point shooter for much of her career, but she's basically stopped shooting them the past couple years).
A drawback/common criticism of Plum though: some *think* she's the queen of getting away with traveling. But maybe refs will see her differently at the next level, or maybe not.
Notably, ~8 ppg this year come at the free-throw line this season, which is an uptick from years prior. Though I think that's just savvy and skill in getting to the line often, and should carry over to the next level.
Looks like she'll a legit WNBA career, plenty long and plenty of production, although on the Pan Ams USA Team last summer, only 12 mpg and 3 ppg.
