I will preface this by saying I have never been in a salary cap league, so my advice may be a bit off considering your league.
Weber....don't drop him. He is a premiere Dman....his numbers will be there at the end of the year.
As for Liles...I'm not totally sold on him. But, then again, if you only have him for a few months, he may be worth the add to see if he and the Avs as a whole keep it up.
Is sanguinetti even playing in the NHL this year?? If you can grab Liles for him and it doesn't hurt your cap you may as well.
