That is about how many goalies the Avs have "in the system" and at the NHL level. I do not count Cash & Grahame in Lake Erie only due to the fluctuation that LE sees in UFA goalies from year to year and the fact neither one are looked to be future goalies for the Avs.
Elliott, Budaj, Cann, Pickard, Patterson, Aittokallio, Millan, and Maxwell make up the potential goalies for the Avs for next season and beyond. Elliott, Budaj and Maxwell all have to be signed this summer to keep them with the Avs. In the summer of 2012, the other 5 need to be signed to be retained as Cann will be a RFA, and Pickard, Patterson, Aittokallio, and Millan will have finished the final year that the Avs can retain their rights as unsigned draftees.
Between the NHL, AHL, and CHL the Avs have about 5-6 spots that their goalies can play. So who will stay and who will go over the next two years (and not taking into consideration any incoming goalies from trades/UFA/drafts)? This is something the Avs are already looking at and preparing for by not signing Delmas last summer (can't have a bunch of available contracts tied up with 3 year entry level deals). Will Maxwell be this year's Delmas? Will Millan be next year's? The future in net looks interesting but outside of Pickard, nothing seems certain when it comes to future Avalanche goalies.
