the Pels are missing their rookie who many exected to be one of the more NBA ready rookies in some time, Derrick Favors who's legit there only decent big (Hayes ain't ready yet) has only played in 9 games, Lonzo has missed 7 games.
Throw in Gentry not being a good defensive coach + half of the current rotation being guys in their third year and under & you get this. Beginning of the season the Pels were losing at the end of a lot of close games... got it together for a nice stretch & then have really slumped the past 2-3 weeks.
with that said they will be fine going ahead, and still have one of the brightest futures in the league.
