Jaylen is clearly a guard, but he also has worse stats than Lillard so he wouldn't start over him anyway. Brunson should be starting with Haliburton.
Jaylen shooting 49% from field, 36% from 3. 23, 5 and 4 with above average defense. Lilliard 25, 4, 7 with 43% from field 35% from 3 with league worse defense for a team with a worse record. Lillard +204, brown +298. What stats are you referring
To? Or was this blind negativity towards Celtics hoping nobody had internet access?
Lillard has superior overall scoring efficiency at 60.3% TS% over Jaylen's 57.8% (average mark). Lillard gets to the FT line a lot more than Jaylen so even though Lillard hasn't shot the ball as well, he gets a lot of easy points at the line. He gets to the FT line at almost twice the rate of Jaylen. Jaylen gets 4.4 FTA. Lillard 8.1 FTA.
Add in Lillard's superior playmaking with 6.8apg to Jaylen's 3.4apg and Lillard is clearly having a much larger impact on the game offensively than Jaylen is. Offensive box plus/minus on Bball-ref has Lillard at a +3.8 to Jaylen's +0.7.
Jaylen is much better defensively. An above average defender vs Lillard's poor defense. Defensive box plus/minus on Bball-ref has Lillard as a -1.5 (bad) and Jaylen at +0.2.
I don't know how I'd rank them overall. I do think it is clear that Lillard has been far better offensively than Jaylen and that Jaylen has been far better than Lillard defensively.
