Lombardi went all in in 2014-2015, 2015-2016 and 2016-2017 and made the playoffs once, winning just one playoff game.
During that stretch he payed the following for rentals: 2015 1st, 2016 1st, Roland McKeown, Martin Jones, Colin Miller, Jordan Weal, 2016 3rd, Valentin Zykov, Eric Cernak, 2017 4th, 2016 5th.
Lombardi was without a doubt the greatest GM in franchise history and he is a really smart guy, but let's not act like he is not 100% at fault for where this franchise is right now. This team that is completely devoid of young offensive talent is because of him emptying the cupboard constantly. He may have eventually stopped, but how many chances does he get?
One more thing, I am actually pretty happy that Dean isn't in charge of our drafts during this tanking season. He had six top 15 draft picks during his tenure as GM, with those the Kings ended up with Jonathan Bernier, Thomas Hickey, Drew Doughty, Colton Teubert, Brayden Schenn, and Derek Forbort. That is not exactly a wild success rate.
