The 16-0 lead collapse exposes a 3-point second-half regression that O'Shea refuses to add

After building a 16-0 lead, the offense managed just 3 points in the final 30 minutes, allowing Edmonton to rally for a 22-19 walk-off win. Mike O'Shea's "no changes" stance means the same personnel will be trusted, but this second-half fade is a fatal flaw against elite closers like Montreal (9-1) in the playoffs.
