Difference between WR and Route apprentice?

Perfect, thank you!

WR Apprentice gives 4 additional hot routes when lines up in a WR position. Route apprentice gives 4 additional hot routes no matter where that WR is line up, for example that WR could be lined up at TE or RB in a special package/set up and still get 4 additional hot routes.

Here’s the hot routes by position they are lined up at: Outside Wide Receivers
Post Corner Corner (C Route) Post Fade Stop Slot Wide Receivers
Cross Corner Post Stop N Go Running Backs
Ghost Texas Flat (Table) Block and Release Hook Tight Ends
Cross Trail Corner Post
