London, who said anything about Simmons, Embiid or McConnell being trash? I think there is a lot of Covington love in this forum too (count me as one of his fans).
Back to Fultz, I want this kid to be good simply because it make the NBA better. And I totally believe that his absence now is due to conditioning issues and the 76ers taking it slow with their investment.
Finally, back to stats - I am sorry but comparing guys (other than what is happening right now) based on what amounts to a handful of games against the scope of an entire NBA career seems silly. If I were able to get the Celtics to make a trade of Tatum for Covington for just the rest of the season and then swap them back after the end, I would think long and hard about it. Tatum's shooting is likely to regress and, as a 19 year old rookie, he is also likely to hit a wall of sorts as the season wears on. Covington, on the other hand, is more likely to be an impact player as the playoffs roll around. Future seasons are another story altogether.
