Well hopefully the offseason theme of stockpiling speedy former 1st round busts, that can play C, is an indication that they're aware of how useless the 'meat grinders' were since the Dallas series.
But since they're seemingly going to place Tuch on LTIR before opening day, they can still add another plug via waivers.
Everything people have said of Howden points to a grinder. I think Carrier, Roy, Kolesar and Howden will be the fourth line in various combos through the season.
2 can play RW, 2 can play LW, 3 can play C. I'm sure they can also play opposite wing when needed. Rotate out to help fatigue, or in injuries. Hopefully none of them (besides maybe Roy) ever have to play above the fourth line, however.
They all seem to fit the big grinder role but they all have some talent and have flashed better. But none of them have any finish.
