Bareroot starts should not be that difficult. Sarracenia should have no problems adjusting. Even with some root damage they should come back in a month or two. Growth patterns vary from species/hybrids. What Sarracenia were they? Are you sure they are dead?
Either the place you have gotten the CPs is selling unhealthy plants or you're making some error in cultivation.
Some one may spot an error if you review how you prepare your potting mixes, how you prepare and handle the potting of the plants, watering and type of water you use etc. Also describe how the plants were shipped, packed and the condition they were in when you received them.
