It's really not clear what you got in Sekac at the moment.
If he comes motivated after a bad season it would make no sense to drop him, not even close, he is probably the best Czech forward out of those playing in Europe (it's between him and Kovar, I suppose). And you want to cut him in favor of guys like Lenc or Cerveny? Or Hynek Zohorna? What a world we live in where those are not only close but people actually pick them over Sekac.. Kinda amazing.
If he just wants to get this season over with then sure, I guess you might as well cut him.
