There's arguably nothing more important in sports than depth.
No matter how good your top talent is, if something were to happen, depth becomes more important than it ever has been before. We've seen teams crumble after losing even their third or fourth-best player because the guy behind them is unable to produce at even a league level.
While fans love to see their team make moves for the top end, elite-level players, making small moves around the margins are the ones that really bring a team from the middle of the pack to elite. Knowing that if your star player goes down, you have someone to step up in their place and continue to help the team win.
