Ceiling is one of many factors in evaluating prospects and players. There is something to be said for a player's floor, as well. Felix Pie, for example, has a terrific ceiling because of his physical tools, but because of how good he is now, he also has a fairly reasonable floor. He's a good defender, has some power, and can hit for decent average. He has a very good chance of becoming a league-average CF because of his current tools. The MLB draft is another beast altogether. A lot of it is potential, but take the following things into consideration: -Signability. Plenty of players drop like rocks because they're committed to college or want lots of money or something like that. In essence, there are questions about whether or not a guy can be signed. -Character issues. PLENTY of guys drop because of character issues, with problems like off the field trouble, criminal records, and drug suspicions hurting how high people are drafted. -The vast majority of All Stars are first rounders. The guys with the best potential are scouted the most intensely and oftentimes find themselves drafted in the first round. Some guys have had baseball scouts following them the majority of their lives. These are the guys teams know the most about and have scrutinized the most intensely. -When it comes to later rounds, matters come down to scouting. Samardzija was a fifth rounder, but because the Cubs dedicated the extra mile in scouting him, they discovered that he could be persuaded from playing football. Other guys like Eric Patterson, Chris Huseby, Andrew Rundle, and so on, who were drafted later were similarly persuaded. So, ceiling's one factor of many to take into account with the MLB draft.
