It puzzles me how many people want to draft/trade for a defensive wing with a top pick.
You don't draft for defense when it comes to wings at the top of the draft, you just don't! You can get those type of guys in the teens and 20's. Not to mention I think Hield will be better than Winslow and I'm not even sure I'd take him with the third pick. Winslow hasn't done jack **** guys come on!! Get off the defensive wings, the team needs scoring we are not going to win games trying to hold opponents to 80 ppg.
Because a lot of people, Danny Ainge included I bet, look at Justise Winslow as more than a defensive wing. He's a kid who shot 42% from 3 as a freshman (Ingram shot 41% this year, as comparison), with a decent assist rate to boot, in addition to playing great defense and a solid performance on the boards. It's not surprising that a teenager shot poorly in his first NBA season, given that the 3-point line is further back. That he was able to be a successful rotation player at that age is a very good sign of his continued development, and I'd absolutely expect him to be a very solid offensive player in the NBA. He may not be a top scoring option on a team, but he's not Tony Allen.
#3 would be a tough price to pay for him, but I wouldn't call for Danny's head if he did it.
I totally agree he will get better but many of the posts I read talked about defense as if it was the reason why you make that trade. I admit I only saw Miami play 10 times this year but at the end of the year Richard(s or son) whatever his name was the other rookie was more impressive than Winslow. Nothing Winslow did made me think he will be better than Smart and I'm not sold on Smart at this point. So me personally would rather roll the dice on drafting at #3. If it was the 10th pick or so than yes I would make the trade.
The point of his defense is as follows:
1) He's a very talented defender. It is rare for a 19 year-old to be that successful defensively in the NBA. He will be an all-NBA defender for many years. That's value. Furthermore, he can successfully guard players from the 2 to the 4, so his defensive versatility is an added bonus. He can play in any lineup your team needs.
2) Defense is half the game, arguably moreso for many players, and it will keep him on the floor. This will help him get more reps on the offensive side, making it that much more likely he reaches his full offensive potential, which is considerable. A lot of the players you look at later in the draft who are defenders first do not have that same offensive potential.
I'm fairly sure that whomever we could draft at #3 will not be as good next season as Winslow will be next season. Even if that player is somehow Brandon Ingram. Being a rookie in the NBA is very difficult. Now, that doesn't mean there aren't a couple of players I could imagine having a better overall career than Winslow, but it's a pretty short list. And again, it's not a guarantee. If Winslow, given what we've seen of him this year, were to enter the draft, I'd put him somewhere between 3rd and 6th on my list for the Celtics. Probably 4th, which is about where I had him last year on my wish list.
I don't think #3 for Winslow is a trade that would make me sure we got the better end of the bargain. I also don't feel we'd have been hosed. Winslow is a very talented kid who's make our team better next season.
