You would not have to necessarily do say, cleans or the like, but a more simple layout spreading what you have over the 3 days might work better and you can put more focus into 3-4 exercises, pushing harder say 1 or 2 of them, than say 7-8 every other day.
You want to try and keep things interesting by seeing gains and progressions happen, so if you load up on too much and cannot see progress, sometimes (if not many times) it leads guys to doing to much switching or CRCing and even worse, quitting altogether.
Simple Example
Day 1:
Squats 3-5x5
Standing OHP's 3x5-8
Rows 3x8
Arms 3x8-10
Abs 2x12-20
Day 2:
Flat BP's 5x5
Leg Presses 3x8-10
Chins 3x5-8
Forearms/Grip work
Day 3:
Deadlift 2x5
Incline Presses or OHP's 3x8
Rows or Pull Dwns 3x8
Arms 3x8-10
Abs 2x12-20
You are hitting the major body's mass and compound exercises 2/2-1/2 times per week. As you get more and more into the program and are adding weight and intensity, you can squat hard say Monday, but do Leg presses with lighter intensity on say Wed. then hit DL's medium heavy that Friday, but then the next week medium up on the squats to hit a heavy DL session the next Fri. This way you can drag a cycle of gaining out longer and add weight to the bar weekly at first (especially on the big stuff) and a pound or so a week on the smaller groups and say arms etc.
As you get more advanced and learn how your body responds to certain lifts etc. you can move into more advanced protocols, add in say cleans or more explosive moves change programs after cycles etc. and such, but IMO it is important to keep the big 5-7 compound exercises always in the foreground, trying to add weight, in order to gain strength and mass (if that is mostly your goals!?)
Also as you get more advanced you may want to break up the W/O's into upper and lower body splits.
