Tanner Glass: Still in the NHL

Yesterday I tweeted that the Rangers are making a huge mistake by holding on to Tanner Glass (well, something like that). I don't normally enjoy making bold statements without anything backing them up, so that's what this blog post is about today. This post is about proving why, objectively, Tanner Glass is one of the worst players in the NHL holding down a regular spot in a lineup.

Luckily for the Rangers, it looks like Tanner is currently the 14th forward on the depth-chart; but for a team that stated all through training camp that they would enter the season with 13F and 7D, and are right at the cap ceiling ($151,000 in cap space), the Rangers were not true to their word specifically to hold on to Glass and his abhorrent $1.45m cap hit.

To be as objective as possible, this post is going to be about how Tanner Glass makes his teammates worse, and therefore makes the Rangers worse. And not just worse, but bad.

A "drop the mic" metric that could end this post in one paragraph?

When the Rangers are shorthanded, they score goals at a rate of 1.4 goals per 60. And to his credit, this also includes shorthanded time that Tanner Glass was on the ice for. Now, when the Rangers are playing 5v5 with Glass on the ice, they score goals at a rate of 1.35 goals for 60. Yes, you read that right. The Rangers are a more prolific offensive team shorthanded than they are with Tanner Glass on the ice 5v5. 

Shorthanded GF/60 - 1.4
Tanner Glass on ice 5v5 GF/60 - 1.35

Drop mic; blog over.

Let's dig a little bit more.

In a recent blog, I posted a chart detailing what I called 'The Glass Effect', which painted a pretty digestible picture about how bad Tanner Glass makes Dominic Moore. Moore, normally one of the league's best 4th liners becomes a borderline AHL player with Glass as a linemate. 

This is not an exclusive event to Dominic Moore.

After Dominic Moore, Glass spent the most time on ice 5v5 with Jesper Fast, and Lee Stempniak:

This is not a phenomena exclusive to Glass' forward linemates, either.

The Rangers have the puck more and score more without Glass on the ice. It's obvious on the individual level, and it's obvious on the team level. 

With Glass on the ice 5v5, the Rangers scored just 33.33% of the goals. Without Glass on the ice 5v5, the Rangers were the team putting the puck in the net 59.55% of the time. This allowed Glass to record the abysmal -26.22% relative GF% he did last season. Only two players in the NHL played as much as Glass did last season and recorded a lower relGF% metric; Tomas Kopecky and Derek MacKenzie (teammates on Florida). 

If you are more of a pure stat fan, then you might be interested in knowing that Tanner Glass recorded 5 points at even strength last season. The lowest point total for a forward who played as many minutes as Tanner Glass did last season. 

In terms of driving offense for his team, if the above paragraphs weren't enough to settle this case, we can view that as well using player usage charts. 

Using relative Corsi for, and relative scoring chances for as our variables (along with a color variable for quality of teammates), we can get a good view of who is helping their team drive offense. You don't want to be in the bottom left. Tanner Glass is in the bottom left; and not only is Tanner Glass in the bottom left, but he cannot blame it on the quality of his teammates, sporting an above average quality metric (blue). 

And if we run the same chart, but just for Rangers forwards last season:

Unfortunately, this is not a new, or 'off-year' occurrence for Tanner Glass. Last season is not an outlier for him. Before coming to the Rangers, Glass played two seasons with the Penguins. He played in all 48 regular season games during the lockout shortened 12-13 season, and 67 games in 13-14 before earning his three-year deal with the Rangers.

12-13 Pens (200 min TOI minimum):

13-14 Pens (400 minute TOI minimum):

And finally, all NHL forwards for the last three seasons combined, minimum 1000 minutes on ice:

Alain Vigneault went on the record stating that he wanted to carry 13 forwards and 7 defensemen to start the season. The Rangers are currently carrying 14 forwards and 7 defensemen. They are strapped against the cap which will severely hamper their ability to make any deadline deals (if they keep the roster this way, which is surely unlikely).

The Rangers front office and coaching staff are limiting themselves to keep Tanner Glass around on this roster.

Why?
