It's interesting to me that so many point out defensive deficiencies of Bagley, while strangely the discussion of Doncic's defense is the sound of one hand clapping. I wonder why? Bagley at least has the athleticism to be a very good defender in the future. But Doncic? Is he the model of the two-way player? I know. You can see the inner Kawhi in there somewhere. I can see how people might be jumping on the Doncic Dallas bandwagon after beating those noteworthy teams like the Wizards, Pelicans, Cavaliers and Magic and achieving second place in the West. After they play the next two games, the Knicks and the Grizzlies, possibly producing a 7-2 record, pandemonium could break out in Doncic Dallas land. Banners will be unfurled. Trumpets will blare. Twitter will explode. Championship here we come!
It's a long season, folks. Those who bash Bagley as a means to vent their frustration about missing out on the Second Coming should give it a rest. At least until we're in the latter half of the 82 game season.
Well I think for starters you can say that both have good/great potential as scorers. Both are good rebounders for their positions as well. However, Doncic's ability to pass & setup his teammates is far superior to Bagley. For starters, I think that's why people are willing to accept Doncic's lack of defense moreso than Bagley. The fact that Doncic can really do it all on the offensive end whereas Bagley appears to be more of a scorer on the offensive end plays a role.
The other thing you need to keep in mind is that defense tends to be more important for big men vs. perimeter players. For Bagley to be a cornerstone that can help lead us to championship contention, he's going to need to be a good defender. Guys like Lillard, Harden, etc. who aren't known to be good defenders are able to still carry their teams despite their defensive inefficiencies. Doncic is seen in a similar light. Let's look at the top championship contenders and their franchise pieces:
MIL = Giannis, Middleton, Brogdon, & Bledsoe. No big men who are bad defenders.
TOR = Leonard, Siakam, & Lowry. No big men who are bad defenders.
PHI = Embiid, Simmons, Butler, & Harris. No big men who are bad defenders.
GSW = Curry, Thompson, Durant, & Green. No big men who are bad defenders.
DEN = Jokic, Murray, & Millsap. No big men who are bad defenders.
POR = Lillard, McCollum, & Nurkic. No big men who are bad defenders.
HOU = Harden & Paul. No big men who are bad defenders.
UTA = Mitchell, Gobert, & Ingles. No big men who are bad defenders.
Big men who are looked at as cornerstones for their team but aren't recognized as good defenders:
LaMarcus Aldridge (48-34)
Blake Griffin (41-41)
Karl-Anthony Towns (36-46)
Kevin Love (19-63)
Love was actually part of a championship team, but that championship team made him a 3rd option and had the best player in the world (and arguably the best player to ever play the game on it). Not to mention Love's shooting ability (which is still suspect with Bagley) allowed him to contribute to that team more than a big that operates mainly around the rim and in midrange.
If Bagley cares about team success, he needs to emphasize his defense and his shooting when picking things to prioritize in his development.
