My experience has always been that deer will walk into a food plot using just two or three trails that can be traced back to bedding areas. Sure, one may occasionally pop out from some other spot, but for the most part, you'll soon learn where they prefer to enter the plot.
No question, if the rut is on and you have doe coming into your plot, they may very well drag a buck with them. Heck, they may even drag one across the area behind your parked truck. Where that hot doe goes, they go. Thy eat very little during the chase phase of the rut because they only have one thing on their mind.
