Well, its obvious by now, but I like Bozeman a lot as a Guard (probably more than most), so I generally try to avoid moving guys to a different position when they're already good at one.
If Cleveland or Powers shows very well in preseason, I'm all for it. My concern is if they don't, then you've got a weakness at LG, in which case I don't know if a TCC/Bozeman combo would be better. It's too early to tell, candidly.
I'm more or less surprised that you're making a position switch like this, and you're announcing him as the starter before you even really start the offseason. Like I get the competition is low there, but I would have expected to at least see how it plays out first.
May be inevitable and likely wouldn't change 3 months from now, but seems very "anti-Ravens" to sort of anoint a starter without ever really playing there in the league. That's like announcing Cleveland is the starter at LG the first day he throws pads on.
