I believe you are correct, the number is 63 and that some scholarships can be split. The last time I spoke to our coach he indicated that some of the scholarships are split.

Our website indicates that the NCAA maximum number is 63 scholarships in football. We do give out 63 - or we did a few years ago according to a chart on our website - the chart hasn't been updated since we cut some teams and reduced the athletic department budget. There may have been a reduction in scholarships as well.
