Found something interesting from MLBTR:
"The Blue Jays drafted Bickford, a hard-throwing prep righty, tenth overall. He was a late riser on draft boards. In their scouting report, Baseball America noted that Bickford "could be a tough sign away from Cal State Fullerton." The Jays will receive the 11th overall pick as compensation next year if they fail to sign Bickford by tomorrow's 4pm central time deadline, under the likely assumption they offered him at least 40% of the slot value of $2,921,400. Toronto previously failed to sign their first-round pick in 2011, Tyler Beede, as well as supplemental round pick James Paxton in '09."
Sounds like they saw something and didn't want to offer him anything close to slot. Maybe they know they need more money to sign the other guys.
