As mentioned, there are a lot of variables for every tournament, most of which are dictated by lake and tournament formats such as one day or multiday, team or pro/am or club etc. Rather than get into this response on a conditional or geographic gameplan, I will comment about Sam Rayburn.....
Very few one day big team tournaments are won unless you have an 8lb+ fish in your sack and even then, you really need to have two fish in your bag that cumulatively equal 15+ lbs together. If you are going after a check and are satisfied with just doing that in these bigger single day team tournaments, very few times does it take less than 17-18lbs to get a check. Catching 17+ is hard unless you have a 5+ lb fish in your bag on Rayburn. Rarely does someone come in with a limit of all cookie cutter 3.5lbers. Does the weather allow the offshore anglers to fish their "spots"... Throw this theory out the window because that is when the outliers show up like 30-40lb sacks.
IMO... Take that bit of advise and fish smart, treating every tournament on Sam Rayburn as a big bass event. Go for that kicker the entire time because at Rayburn, if you don't get that big bite or more importantly if you are trying to win, multiple kickers, then you will be in that 10-13lb purgatory that 80% of the anglers that catch 5 keepers on any given day get stuck in whether they are in a tournament or not.
