I disagree that Ceci is an established top pairing guy in any capacity. He's just put in that role in Edmonton because there's no one better.
Feel free to disagree. That's how the Oilers have deployed him essentially since his signing. Historically, his time on ice deployment is:
Ottawa: 440 games, 21:04 toi average
Toronto: 56 games, 20:32 toi average
Edmonton: 203 games, 20:27 toi average
Only Pittsburg 53 games did was his toi average below 20 minutes at 18:31.
His career zone starts tilt heavily to defensive zone: 64.3% over 3 years in Edmonton. 60.5% over 6 years in Ottawa. We see him have consistently high PK toi which is a critical quality time of ice situational play.
Strangely, I've consistently for over two years have argued, and still argue in all of my posts including one you have replied to, that I firmly believe the Oilers top priority is a top 4RD... which of course would mean replacing Ceci. Doesn't change the fact that Ceci on a $3.2 million AAV has been deployed as a top pairing guy. You're arguing against yourself.
