He could be but consistency is still a major issue. We'll see next year. He was very up and down his first two seasons as well, starting off bad and then playing better during the second half of the season.
He certainly could be top 5 next year but i wouldn't put him there now just because of 5 weeks of strong play. It is very encouraging though, especially since he was crap in feb.
You want to compare an almost 23 year old to a just turned 21? Let's not even talk about the extra year of experience in the NBA.
I don't think Wall is better than Irving either (Wall needs to produce like this over a longer period of time--PG position is too deep for a month to push someone into the top 5), but is that seriously an argument you tried to make?
If that's the case then it would be impossible to compare any players who aren't from the same draft class with the same age.
