You are just egregiously wrong.
Girardi has been recognized as a top Dman in the league by his all star selection, his Norris rankings. This is not something new.
These are his numbers the last 3 years

He is workhorse, who has missed 4 games in his entire career. He's a warrior, plays hurt ... Broken noses. Stiches. Big injuries that would sideline many other hockey players. He consistently plays against the opposition best players and shuts them down. He brings it every night.
29 years old. A very likeable teammate. Someone who doesn't carry any baggage either. Great locker room guy and one of our Alternates.
Girardi is underrated on these boards because he doesn't have the sexy offensive game, it still doesn't take away from his outstanding shutdown D.
Anybody can have a different opinion of Girardi, but the numbers don't lie. They point to Girardi as a top shutdown Dmen in the league.
Why are you listing hits and blocks? Awful statistics to use when evaluating a player's value. Can be used to identify style of play, but being ranked high in hits and blocks (and takeaways) is actually a negative indicator of performance as you need the other team to have the puck to record such an event.
Let's do an in depth analysis. I will try to be as objective as possible.
Hypothesis: Dan Girardi has made himself a name in the NHL by playing with two fantastic partners in Marc Staal and especially Ryan McDonagh.
Let's look at the past three seasons in reverse order starting with 2012-13:
Last season Dan Girardi was primarily partnered up with McDonagh for ~430 minutes of zone start adjusted 5v5 ice time. In those 430 minutes the Rangers did as follows:
GF60: 1.812, GA60: 2.508, GD60: -0.696
CF60: 61.44, CA60: 58.80, CD60: +2.64
So the Rangers were significantly outscored with them on the ice. However, they played very tough minutes and the Rangers were unlucky with the shooting percentages last season, they did at least slightly control the play. So let's examine how the two players did without each other for comparison. Girardi played ~320 minutes without McDonagh, McDonagh ~370 without Girardi.
Girardi without McDonagh:
GF60: 2.073, GA60: 1.320, GD60: +0.753
CF60: 59.34, CA60: 63.87, CD60: -4.53
So Girardi actually performed better in regard to +/- away from McDonagh. But due to the short season I would downplay goal based stats as the sample gets so small, and the Rangers were unlucky with percentages last season. If we downplay the -0.696 they had together, we also have to downplay Girardi's +0.753 away from McDonagh.
Girardi's possession numbers took a big hit away from McDonagh and the Rangers were instead spending more time in their own end with McDonagh-less Girardi.
So how did McDonagh do without Girardi?
McDonagh without Girardi:
GF60: 3.705, GA60: 1.287, GD60: +2.418
CF60: 62.34, CA60: 49.29, CD60: +13.05
Wow, those numbers are gaudier than I expected. The Rangers were crushing their opponents, both in regard to goals scored (less relevant) and in regard to possession.
Conclusion: Girardi had a pretty brutal 2012-13 campaign.
But what about 2011-12 when he was an all-star?
Girardi and McDonagh spent ~1230 minutes of zone start adjusted 5v5 time on ice in 2011-12.
Girardi with McDonagh:
GF60: 2.535, GA60: 2.193, GD60: +0.342
CF60: 48.15, CA60: 50.55, CD60: -2.40
As a pairing they managed to come out ahead against top competition while being slightly outpossessed, an overall good job on a less dynamic Ranger team.
Now let's see how they did when apart. They spent a lot less time apart in 2011-12 despite the full season, both players played ~210 minutes away from each other.
Girardi without McDonagh:
GF60: 1.722, GA60: 2.871, GD60: -1.149
CF60: 46.80, CA60: 54.84, CD60: -8.04
Girardi had a very tough time away from McDonagh in 2011-12. The GD60 being over -1 is alarming, but goal based stats from only 200 minutes is very unreliable data. The Corsi data is more reliable due to the higher number of counted events, but it still looks bad there.
McDonagh without Girardi:
GF60: 2.874, GA60: 1.437, GD60: +1.437
CF60: 55.74, CA60: 56.91, CD60: -1.17
McDoangh once again improves his performance significantly away from Girardi. His GD60 is once again fantastic, outscoring his opposition 2-1. But still the less significant number due to sample size. Only a slight improvement in regard to possession but the 11-12 Rangers weren't, as earlier stated, a dynamic team.
Let's move on to 2010-11, Girardi's breakout year where he anchored the top pairing with Staal.
The pairing spent ~890 zone start adjusted minutes of 5v5 play together.
Girardi with Staal:
GF60: 2.286, GA60: 2.691, GD60: -0.405
CF60: 49.62, CA60: 52.44, CD60: -2.82
Outscored and outpossessed, but they faced very tough competition on a mediocre team. Not bad.
So how did they do apart? They weren't tied to the hip as much as McDonagh and Girardi in 2011-12 and both of them spent ~390 minutes apart.
Girardi without Staal:
GF60: 2.616, GA60: 2.769, GD60: -.153
CF60: 49.23, CA60: 63.69, CD60: -14.46
So Girardi's GD60 went up away from Staal, but as you should know the sample size heavily affects this figure. His possession numbers were on the other hand remarkably bad, they really surprised me. Overall a significant decline when away from Staal.
Staal without Girardi:
GF60: 2.325, GA60: 1.86, GD60: +0.465
CF60: 49.59, CA60: 51.45, CD60: -1.86
Staal when freed from Girardi improved in all aspects. His significant GD gain should not be emphasized much and he only improved slightly in possession, so overall a slight improvement away from Girardi.
Just as a bonus I will include McDonagh's numbers away from Girardi in 2010-11 over ~510 minutes:
McDonagh without Girardi:
GF60: 3.753, GA60: 2.463, GD60: +1.29
CF60: 54.30, CA60: 51.39, CD60: +2.91
For a player on the 2010-11 Rangers, fantastic numbers all around. Incredible performance from a rookie mid-season call up.
To summarize:
Girardi showed a significant decline in his game whenever separated from his partner, while the partner in question showed significant improvement after separation. Hypothesis confirmed.
Girardi's numbers actually took a bigger hit than I expected. I thought the 2012-13 numbers would be the worst, but they turned out to be the best!
How about trading Girardi to the Devils for Fayne? Any takers?
