Jimmy Howard wasn’t sure where he’d be playing this season. As it turned out, it was in Detroit. Heading into the summer, there was talk Howard would be traded, with Petr Mrazek the clear starter in goal. But in a tight market with few teams needing established goaltenders — and three years and $15.9 million left on his contract — Howard proved untradeable. “Not disappointed, that’s for sure,” Howard said Wednesday. “I’m happy I’m here. I didn’t really want to leave in the first place. My family loves it here. I love it here. I have great friends in the (locker) room. “I’m happy to be back.” When last season began, coach Jeff Blashill left the starter’s job up in the air, with Mrazek assuming control in late December as Howard slumped.
