True...but we're still talking about Radford. RPI 150 last year
If you schedule a game with Radford, you automatically get their Winning % and their Opponents' Winning % in your own RPI. That's 75% of the calculation in the game's value. Then you can add 25% by winning the game. (Yes, I realize that home and away are weighted slightly).
Playing a bad team is bad for your RPI, and only slightly better if you beat them. It's not crushing to lose that game.
tl;dr - 75% of the RPI value comes from who the opponent is whether you win or lose.
EDIT: Sorry, but this is a pet peeve of mine... imagine you were playing 2 teams on a neutral floor, one with a great RPI and one with a terrible RPI... there is no difference between going 1-1 while beating the great one and going 1-1 while beating the terrible one. People act like losing to the terrible team would give you a worse RPI... that's not the case.
