Unfortunately, several of those defensemen are not exactly NHL vets.
Here's how things look:
Tallinder - Lydman
Rivet - Butler
Montador - Sekera, Weber, Myers, Paetsch
While a player like Paetsch that plays both forward and defense can be handy to have in a pinch, I'd be willing to part with him, with the abundance of young talent the Sabres have. Talent that appears to match or exceed Patches' skill set.
Looking at that line-up, not much appears to be coming from our defense in terms of offensive output. Without being hampered by such trivial things as looking up "stats", I'm fairly confident that none of the players that spent a full season in the NHL registered more than five goals apiece last season.
While my heart wants that 6th spot to go to Mike Weber, I have to make a case for Andrej Sekera. One of his (alleged) top assets is his ability as a puck-mover, a talent that cannot truly be boasted by any of the players listed in the top 5. Perhaps Sir Christopher will up his offense this season, and Myers has definite talent in the area of a strong first pass, but none of the NHL veterans are known for their offensive output.
A continual complaint about last year's defense corps was their lack of contribution on the scoreboard. Based on the way things are looking now, that doesn't seem to be about to change any time soon.
Let's get rid of Tallinder and then we can have this:
Lydman - Sekera
Rivet - Butler
Montador - Weber
That's not ideal, but I like it better than the list above.
