Ray Allen is less than 100 3s away from Reggie Miller!?

Ray has 2472, Reggie Miller has 2560. Ray is bound to surp Reggie this season, unless he gets injured or all of a sudden he forgets how to shoot. When do you think it'll happen? I'd say in around 35 games (He usually averages around 2.5 3s a game). When he pes Reggie, is he going to be considered as greatest shooter of all time?
