Monica is more on the block and can rebound for you. Luc will rebound and also has that little foul-line jumper. They know their role - they do a few things and do it well. They do the dirty work - bang, use their fouls. They're enforcers and will protect their players.
Every team needs a consistent player like that in the hole.
They are defensive, backcourt specialists. Their job is to pressure the ball for 94 feet - to try and disrupt your rhythm. They will give you different looks, are always hawking the ball and have a lot of tenacity. If you have somebody like a Henning or Harper that can make you set your offense up two feet higher, it will disrupt the timing and the angles. They also generate a lot of offense off their defense because they get steals.
