Trouble getting under the 85 limit?

The current number of recruited players on scholarship break down as follows:

Class of 2012:  10

Class of 2013:  20

Class of 2014:  15

Class of 2015:  13

Class of 2016:  29

Transfers:         2  (O'Korn and Isaac)

Grand Total:     89

This means M needs to shed 4 scholarships between now and fall camp.  But who?

I think there is an obvious one not getting his 5th year.  But that still leaves us with 3 other potentially messy partings that could bring more bad press to Harbaugh.

I'm a bit worried about this.
