Jonas’ article today had some good insight into Cooper’s strategy from last playoffs (and likely this one).
Sheldon Keefe said O'Reilly has "done really well" with every assignment, but where will he most benefit the Leafs in the playoffs?

Basically that when Tampa was at home Cooper targeted Tavares’ line and the results resoundingly favoured the Lightning against him. With that in mind, it may be prudent to have two lineups in the playoffs, one for home and on the road. O’Reilly could centre his own line at home to matchup against Tampa and let Matthews’ and Tavares’ lines go up against weaker competition, and on the road Keefe could move O’Reilly up to centre Tavares and protect him and the Leafs from matchup problems.
