According to Steve Zipay and the Blueshirt Banter the Rangers are giving a qualifying offer to Restricted Free Agent Brandon Prust, but not Erik Christensen.
No worries though, the Rangers are thoroughly interested in both. Prust will more than likely receive an offer between $550-600,000, a slight increase from his $500K salary last season. This reassures that if anyone was to get Prust and he signs an offer sheet, we would get compensation for him. Compensation varies by the amount officially offered.
Christensen is not getting one, because the Rangers want to sign him to a two-year deal rather than the automatic one-year the QO would give him. This plays a little risk game, because once July 1st comes, he becomes an open free agent. Like I said in my 2010 Free Agents section though, the idea is that because he passed through waivers before, not many teams are interested in him. Why a two-year deal and not just strap down a Center we need you ask? Well rather than paying $850,000 this year, signing him to a multi-year deal will lower that number and make the signing much more economical sense for this salary cap rubbing team.
