Well, you have to remember that in the English department they do teach folks to write for public consumption. Like how to write novels and stuff. But yes, other than that, you are absolutely right.But not in a paper unless you’re quoting someone.
If the whole thing was written that way I would hope the professor grading it ran out of red ink.
The standard is just that, the standard.
The player doesn’t decide when it’s a first down. The referee (the instructor) and the rules of the game (the “standard”) do.
