I would think the Rangers are waiting to see how training camp plays out with the younger D--notably DeAngelo, Bereglazov, Pionk and Graves and maybe even Day before they make a decision on what to do with Holden. Even Staal's play during training camp might factor into that. Having two rookie D playing regularly as well is not a thing that most competitive teams can get away with. But anyway I don't suspect Holden is going to be moving until more is known.
On Zaripov and Jagr--I have doubts about both and if I signed either I'd keep the term down and $2 mil or under. They are both risks AFAIC. The Rangers do need more forward depth though.
They ended up with two rookies on the roster in 2010-11 and also had 2 sophomores there as well. After Rozy got dealt, Girardi was the oldest D at 26 until they brought in McCabe. They traded Rozy after he got hurt and McDonagh came in and essentially stole his spot.
So you may be right. I don't think the idea of two rookies is a big roadblock, but the team might want to make sure that two rookies are even capable of playing first.
