When news articles mention the maximum, especially in headlines, it feels a bit misleading. It seems there's a decent chance there is little or no prison.
A reasonable estimate based on sentencing guidelines isn't super hard for a lawyer to work out, and it'd be far more useful for readers, but it's slightly more work and it makes for significantly less exciting headlines.
Sentencing is a fairly well defined things. You have guidelines and upper limits that come with specific charges, and then the judge uses those guidelines and various other factors to then sentence somewhere along that spectrum. Anyone read a handful of sentencing news stories is very well familiar with how it works.
