In general, current league draw group teams with similar qualities together, this may be exception but I also saw 1 or 2 exceptionally strong or weak teams for several times before
If your league is a league with relative low quality teams, say average 3 star or 4 star, on Day 3, teams are easily upgraded to a team like this because they can simply upgrade by buying 5 star players.
If the team keep several very low quality 1 star players before league draw in order to lower the team average and then sold these few players after drawing, their team may also be looked like this now.
In real world, rich teams also groups with poor teams in some leagues. Rich people also live in same world in poor persons like me. This is reality.
