When you take the teal-shades off, this is what you'll see: last year's center gets moved to right guard for a 2nd round rookie (as opposed to a supposedly "can't miss" Top 5 rookie) and the left guard is an aging FA not resigned by his previous team. That's NOT a prescription for interior OL excellence when there are teams like the Pats and Chargers that return all their starters, all of whom are proven, quality veterans.
A lot of teams prefer to take OL later in the draft, looking for raw talent because lots of college teams don't teach the OL skills the pros need, but that means that it takes a while for these youngsters to come up to snuff -- usually takes 2 or 3 years, and the lower the draft round, the longer it generally takes. I don't know if Satele fits this model, but some of Miami's other young OLers fit it. It's just not realistic to think that these guys are going to be able to step right in and play well.
If the Fins' starting trio proves themselves, then they'll get ranked higher, but at this point, the ranking seems fair.
