Sure if you ignore cap hits - it would be a no-brainer. I wouldn't want Rome @ $1.6 million (given the current cap structure of our blueline - he'd be too expensive IMHO).
The difference in cap hit isn't that great, $275K. Alberts is useful when you expect, or want to impose a slower, more physical game, but he is really exposed against any kind of speed. Rome is almost as physical - what he lacks in size he makes up for in aggressiveness - but Rome can actually play every day if need be. He's no Jason Garrison as a skater, but he's mobile enough and has good enough positioning. Yeah, he's a drop off from Ballard / Tanev skillwise, but if someone is injured you can insert Rome without having to totally protect him.
I guess I'll have to be patient and see if the Rick Bowness can revive Cam Barker's career or if it is just a cheap experiment.
