It doesn’t make you pay more. It makes you pay for longer to the same players, to encourage retention and continuity.
Pay a guy $1 million in 2026, pay his replacement $1 million in 2027, then pay that guy’s replacement $1 million in 2028.
Or, pay one guy $2 million over 2 years or $3 million over 3 years - structured to where he gets most of the money when he’s actually playing meaningful snaps. If its a HS kid, do $500k freshmen year, $1 million sophomore year, $1.5 million junior year. It’s the same money as the above example ($3 million total), but less required up front, and you’re not paying much to guys to sit on the bench.
