I believe you control what YOU can control. You've got no idea where other teams are going to fall, and how the standings will shake out, ESPECIALLY in such a close playoff race.
I think it's a losers mentality to try to position yourself for an easier matchup. You win as many games as you can without running your players into the ground, and giving them the adequate rest to be healthy for the playoffs.
Obviously a lot of people probably want the easiest path to the Finals, but I think having a hard series to start off is a great way to keep momentum in the playoffs, especially if this team can finish the remainder of its games at even 75% of the winrate they've had over the last two months. Going against an easy opponent that ends in 4 or 5 leads to a longer layover between series, and I've seen that bite a lot of teams on the behind in the past.
