I just told you the numbers... you can look them up if you want exact.
Here are ray allen's
Ray Allen
Here are steph curry's
Stephen Curry
You'll note that Curry has more steals, has a higher steal percentage in opponents' possessions, has better defensive win shares, has a better defensive rating on average AND is trending better than allen ever has...
If you watch basketball, you'd see how disruptive curry has become. He's not a lock down defender, by any means... but he now does a good job tracking his man, and has become much more adept at leaping into passing lanes AS WELL as ripping opponents dribbles, and sneaking in to rip from slashing/posting players.
Here's something you clearly haven't learned about me. If I tell you it's my opinion, it's my opinion. Everyone has them, and I've been wrong plenty.
If I'm telling you the numbers back it up, I don't do that without knowing the numbers. That's a little free-tip for all you JV posters.
