For all intents and purposes, the starting lineup at the WR position really doesn't mean much.
After all, back in 2017, the starting WR's were:
Freddy Canteen
Cameron Smith
Equanimeous St. Brown
Out of those three, only St. Brown logged significant playing time, given that Canteen was already an injury plagued wreck from the start, and Cameron Smith got quickly replaced by Miles Boykin and Chris Finke.
