A big buck will always follow that 1 doe that just passes out of range and never the ones that are close enough to be killed with a slingshot!
Have confidence in your scouting and hunting abilities....no matter how frustruating it is to watch the same 3 1/2 and younger bucks all season, a big one can change your season outlook at anytime, even if you don't get a shot! I had not had an encounter with a 4.5+ buck until 11/16...a long 6 weeks of bow season. From 11/16-11/22....It's been my best bowhunting of my life and I haven't even loosed an arrow....yet. I've seen 3 different bucks that would rival or exceed my best bowkills including a giant 10pt w. a 10"+ drop that would make you think I lived in IL!!!
