Obviously real teams have their own scouting system, and the Cubs have more actual scouts watching more games by the top 15 candidates that BA, BP, and ESPN put together. The amount of views and cross-checks reviews will be way more extensive. And the number of intelligent voices in the room discussing the pros and cons for each player will be way more extensive than in Wilken drafts past. All the Cubs brass are heavily invested in getting it right with the top pick. MacLeod, Hoyer, Theo, the scouting director, the area scouts, the top cross checkers, Wilken, probably last year's scouting director, probably all of those guys will go to watch some of the main candidates. Or perhaps have video and computer breakdown on all or many of their games, even when they aren't in live attendance.
Hopefully when they identify and rank their top 5-6 guys, they'll know what they are doing. And if they wander from the seeming "industry consensus", it will be because they know better and they are right.
