The original WS4SB on the 3 day a week scheme would be less taxing than starting strength.
The 4day a week version of WS4SB is also less taxing than SS.
Squatting 3x a week plus heavy deadlift, power cleans, chins, benching, and pressing on starting strength is just exceptionally taxing.
Neither version of WS4SB is going to make your squat, DL, bench, and press go up like SS.
WS4SB 3 day isnt as good as the 4day IMO but the 4day takes a lot of discipline to keep up with.
If you can manage it I would try to wrestle and do SS on the same day, doing SS first, preferably in the morning with a long break before wrestling. You will be tired in wrestling but that will force you to focus on technique, and give you complete rest days between lifting days.
If you only want to lift twice a week neither of these programs is a good fit.
Edit: by "for athletes" he means its a good bulking and general strength program for athletes with an off season, since you can gain a lot of weight in that 12-16weeks off season if youre nutrition is totally in line.
