Those are definitely guys who left their team mid-season.

Bagnah had played in the weeks leading up to that, including just the week before he left.
Kingsley had only played in one game that season, but was listed on the 2-deep.

And they both left their teams in the middle of the season. But that's the point; as fans we're all VERY aware that Holker left mid-season and judger him for it - because he left us and we were very aware. But most of us don't know or care that Bagnah quit on his team midseason, because we weren't watching Boise St close enough to note it. Most of us just think he was a normal transfer
