It’s inherently unfair to compare a completed career vs one that’s just starting. Tatum is a better player than Pierce if they were on the same timeline. He has more talent, a better shot, a better handle, a better rebounder, and probably a better defender due to his size. Pierce also wasn’t always the “leader” he eventually became (Walker was more the leader then, I’d say) and he was probably more immature than Tatum iirc.
The edge Pierce has over Tatum are: drawing fouls and clutch gene. Sure, Tatum has made some big shots but Pierce always had “it” in my eyes. Like I always felt like the Truth was always going to make the big bucket down the stretch. Can’t say the same for Tatum. Admittedly, I might be biased on this because I’m a big Pierce fan.
Build a franchise around: Tatum
Take the last shot to win it all: Pierce
