S6 screen glass replacement

So I have been wondering whether or not should I buy a screen protector for my s6 I love the feel of the phone,also I hate screen protectors in general.Anyways,I was checking the price of the screen glass which is around 22$ but the digitizer 200$.Is it possible to replace the screen glass only without the digitizer? If yes,what are the odds of breaking the digitizer if the phone falls from my hands?I was willing to buy a transparent cover only when I go out.
