Lyles is 20, Favors is 25. The offensive potential of a team with 4 floor spacers compared to 3 floor spacers is enormous.
Clogged lane in the NBA = death sentence. You gimp the effectiveness of any slashers on your team, which on ours is a bunch: Burks, Hayward, Exum, Hood (sorta)
Also Favors is a good defensive player, but not close to great. His defensive RPM the last 3 years: 1.80, 2.18, 1.61
Ultimately, I think it comes down to this. Is Favors good enough we want to try and buck this?
