You have to look at the profile of the players - he does this in the later rounds as well -Vosean Joseph for instance. RD1 definitely Beane loves the athletic high ceiling guys. He has said in a past interview last year , he grades the guys in RD1 as Top-tier, Mid-tier and Bottom-tier. He likes to move around as well, with the Edmunds pick , they had him identified as a top -tier guy and were trying to move to 14 to get him. He said if a top tier is falling and if it is s position of need, they would be aggressive and get him, if it wasn't a position of need - they in most cases wouldn't move.
Beane doesn't give a lot of info out, but he doesn't lie and he is proving to be consistent in his thinking and moves....
