They both involved the same guy. Stacey Augmon tried to steal the inbounds from Elie, I think, causing Sheed to rotate to block Elliott's shot.

Versus Detroit, Sheed doubled down on Manu in the corner, forcing Prince to come from the lane to try to block Horry's shot.

So Sheed was involved in both.

Yes both very similiar, the only real difference was that the ball went directly to elliot on the inbounds pass and he was way less open than Horry. That would be the only reason I would give it to elliot as the best clutch shot in spurs history.
