Very early so we gotta give it more time. Lets see if they can get it going here over the next few games, cuz i think the other 3 lines will be just fine. I love the energy in that Carcillo - Kruger - Morin line. Very nice 4th line if they keep it up. When Versteeg comes back maybe try him on the 3rd line with 29 and 91 and move Smith back down to the 4th line. Either way gotta give it time, especially with Richards, to see what the best combos will be. I think eventually we'll find a 3rd line that will click.
Other potential scenarios might include TT being called up sometime later in the year and joining the mix. Im not sure it will happen, but if he really impresses at Rockford and gets a temporary showing with the Hawks because of a short term injury, he might prove he's too good to not keep around, and then earn a permanent spot over either Morin, Carcillo, or Versteeg.
