How costly to the Blackhawks was the Seabrook - Chimera fight?

Given Brian Campbell wasn't playing, it knocked them down to only 4 dmen for a good portion of time, so it was pretty costly. Granted, the contact was pretty minimal (Crawford definitely finished first in his class at the Sidney Crosby school of diving). However, losing Chimera's grit, energy, and speed also hurt the Caps a bit. Did it cost the Hawks a win? No. But it definitely made it harder (granted, that hooking call at the end was pretty soft; i saw 5 or 6 hooks/slashes against Ovi that went uncalled which were much harder fouls in the game), so the refs must've felt they "owed" Chicago one (I hate refs like that. If you mess up a call, you don't make a bad call the other way. 2 wrong calls don't make a right call)
