It's also an assessment that Buium brings nothing unique to the table, that is, he's better than the smaller D-men they had, and would be a good player, but not special. If they thought he was 1D material his size wouldn't have mattered. This was a polite way of saying that.
Briere said they had Jett in the same tier as Buium.
That's how teams usually organize their board, ordinal ranking is too arbitrary.
"There (were) other good players in that area, also, that we were considering,”
Briere said via PHLY’s Charlie O’Connor, “but
there wasn’t a big enough difference to go in a different direction."
Which reflects something I believe, it's easier to find smaller puck moving D-men these days (probably b/c they get more opportunity to fill that role at lower levels, the way QBs pass far more at lower levels than a couple decades ago).
Big mobile two way D-men with a complete skill package are far harder to find.
