Weight gain and hockey? So I'll keep it short; I don't eat 100% healthy but I don't eat pure junk- I drink beer , but I play hockey 3-5x weekly .. Mostly pick ups fast paced .. I don't lift weights

Well I'm gaining weight but I don't feel like its fat but since I'm also not lifting I don't see how it couldn't be ?  Am I just oblivious to my diet / caloric burn ratio? Could it be good weight without lifting?
