From an earlier Post I did:
"Giannis, Age 19:
77 games, 24.6 MPG, 6.8 points, 4.4 boards, 1.9 assists, .44 from 2, .34 from 3, .463 EFG, .68 from line
Tatum Age 19:
80 games, 30.5 MPG, 13.9 points, 5.0 boards, 1.6 assists, .475 from 2, .434 from 3, .538 EFG, .82 from the line
Tatum is a far better and far more efficient player than Giannis at the same age. In fact, while Giannis took a major leap to .51% from 2 his second year, it has taken him four years to get to Tatum's Rookie efg of .538, he's still behind Tatum in FT% and three point %, by a wide margin.
It is hard to tell what Tatum's ceiling may be but with another 10-15 pounds of muscle and another year of experience he may well be in the Zone of where Giannis is today, given the minutes and shots.
Lastly, and perhaps most importantly, from what I've seen it appears that Jayson may be more of an alpha dog mentally. He looks like he has that killer instinct, along with elite shooting, something Giannis sorely lacks."
While I like the numbers comparison (or I wouldn't have posted it in the first place...) the most important part is the last paragraph. Tatum is a barely 20 year old rookie posting 25 a game in this series. He has ice water running through his veins (acknowledging he was tight at the line down the stretch tonight...) but you can see that he wants the ball when it matters most and he has elite shooting skills, offensive moves and ball handling for a guy 6'9.
No, I would not trade Tatum for Giannis. I might try to add Giannis to Tatum if an opporutnity presented itself though- that could be fun.
