No, it's not.
It's only a deep question for subjective cappers, who have very little chance of winning long term, save the few talented ones.
Objectively handicapping will eliminate this "question" and keep things much more grounded, whether you've seen the line or not.
Don't use emotions to handicap, especially if you are trying to visualize something...and being influenced by the line while handicapping is emotional. Allowing the line to influence the decision to bet is not the same thing.
It's a game of numbers and numbers is the game.
Everything else is just gambling.
