Exactly.
Under no other circumstances a rider like Groenewegen would work for you. To be a part of your sprint train. That is under no other but his current situation.
It's his ticket back. Public will never accept his wins again if he doesn't do some penance beforehand. As for what his contribution would be is to secure the wins for van Aert in the last 500m or so. Nothing more or less than that. As a consequence Dennis could focus more on his main objective.
All in all if i would be van Aert i would likely take Groenewegen. As Groenewegen could make a difference for me. Up to that 500m van Aert can hold his own anyway. Where he is lacking the most is that final 50(0)m or so.
