Could make sense if "at every position" means at every level, rather than at literally every position. Having 2 or 3 of the best U23 attackers, 2 or 3 of the best U23 midfielders, and 2 or 3 of the best u23 defenders, could be hugely successful with good experience around them.
If that means 2 or 3 of the best LBs / CBs / RBs / etc., then that's really dumb...unless you're including your academy and getting very loose. Having an elite 16/17 and an elite 22/23 yo at the same position, is tenable...even if that's not tenable at every single position no matter how much money you throw at it.
