Mentally weak?

What about Pat Valenzuela or Chris Antley or pre conversion Pat Day or Julie Krone or a host of others that I can't recall who have had problems to overcome. Where they lesser jockeys because of it? To my mind the best jockeys have a sensitive side that is necessary to communicate with the horses. I don't think that makes a jock mentally weak. I'll take Sellers any day and I know he'll get what the horse has. Bailey on TCE gives the horse no boost. He's a closer and Sellers has had him on the right paths.
