Saints' Alvin Kamara named Sports Illustrated’s Breakout of the Year

I'm not understanding this award.

First off, strange title for an award. Breakout? How about breakout player?

Secondly he broke out as a rookie and established himself as arguably the best multi purpose back in the NFL.

Certainly there are much better candidates.
Pretty sure that they consider a rookie season as just that...a rookie season.
And a breakout season as 2nd year or more.
Kamara hasn't had much drop off from his rookie season. Pretty much showed true grit when Ingram was suspended.
