Yes...but anything over about 60 in ST3PT makes that guy a viable 3PT shooter...especially if the guy on the sticks is a good shooter and has a player's release down.
It's not like he's going to consistently make them though...if someone is relying on Olajuwon to bury 3's...they probably aren't going to beat you.
As far as the actual ratings go though...this is another example of 2K being LAZY.
In '94 Olajuwon made 42.1% of his 3's....although it was only 19 attempts. So the 63 rating is pretty fair. However, they then applied the same 63 rating to '90 card...even though Olajuwon was only 1 of 6 on 3's that season.
My guess is they had to do this to make that card rated higher...ugh.
Then on the DPOY card which is based off the '93 season...they dropped Olajuwon to 40 because he was 0 for 9 on 3's.
Doesn't seem right...but it's 2K...so it's to be expected, I guess.
The Diamond Olajuwon's 3PT ratings are inflated. The other cards seem accurate based on the stats.
