I posted a while back about trading for both Petry and Myers. Both are flawed. Both are on shorter deals (Petry for 3 more years, Myers for 2 more years). Both are better options to partner with Dahlin and Power than anyone else in the organization, and won't cost much to get.
They both could mentor the young defenders, and by the time the Sabres' training wheels are off, their deals expire. Seems like a decent development option.
I suspect there will be pushback on these since there is a lot of people who want perfect rather than done.
