Jesuit doesn't get the same kind of athletes that it did once before. There could be a number of factors surrounding this: administration, tuition, inexpensive options, athletic focus (Folsom, Del Oro, Granite Bay, Rocklin, Grant, etc.)
Somethings been going on over at Jesuit for some time. Notably Worrell Williams and Aarik Armstead both transfered from Jesuit and received Pac 12 Scholarships. One can only surmise what happened to Isiah Bailey's recruiting. At 6'3 215 he would have easily received a Division 1 scholarship at Grant or Folsom.
