Eh, BPA can be subjective based on what attributes scouts and GM's value.
After Celebrini, and then maybe Demidov, there's 9-12 players all ranked around the same level and Iginla's right in that group. So if you're deliberating between a potential top center versus a top pairing defenceman versus a top line winger, organizations needs are definitely going to come into play.
Regardless, we're getting to the point where Iginla's giving up strong 2016 Tkachuk vibes in that he's getting grossly underrated by a select few because of his last name.
