While the Trail Blazers have attempted their share of "Hail Mary" inbounds passes over the years, it’s not something they every work on in practice.
There are relatively few opportunities to utilize the play, it requires an element of improvisation that is hard to recreate in a practice setting and when you have a player like Damian Lillard, who is more than capable of hitting set shots from halfcourt, there just isn’t much cause to use precious practice time working on a set that, even when executed perfectly, is still going to be a low-percentage proposition.
But while all those things are true, there’s another a reason, plainly stated by CJ McCollum, why there’s always a chance they’ll try to pull off a full-court heave to beat the buzzer, as was the case to end the half in Wednesday’s win versus the Jazz in Utah.
