But weigh it. The best quarterback available might not be much better than the second best quarterback available. If a much better overall player is available at another position, you might want to pick up that player instead. If your specific position need can wait another round in favor of a better all-around player, then you have to pull the trigger on the better player. Just keep this in mind and you should be fine at draft time.
Some people strongly believe a good quarterback can be picked up from the mid-rounds and on.
I partially agree with that. I feel it really depends on depth at any position in any given year, and the different scoring methods for each league. Point 6 might help you to decide more definitively. The specific league's scoring system can help you determine what players to draft immediately. Some leagues give you a small scoring advantage at certain positions, intentionally or unintentionally.
