They may want to look at giving Cozens Peterka. As much as we love that first line, Quinn can benefit from the time and space Tage and Tuch create, could get him going. Peterka makes the second line immediately dangerous at any given moment.
This is a dangerous road, why change something that works well. There is a risk of getting two bad lines in the top 6 at once, Peterka's energy helps the first line a lot, especially since Touch is not in an optimal state and seems not so fast now, putting the slow Quinn there. Also, Peterka may not help Cozens to understand his cockroaches in his head, although in theory it could work, but I don't want to change the first line.
If Cozens and Quinn can't figure things out in the next few games, then it's up to Adams to make the decision. While Lindy could potentially put one of them in the press box for a few games, that hasn't happened yet.
