Great read. Everyone asking about limits on players (I am sure this weeks ISD ND Power Hour will discuss it ad nauseum) should take a look before filling up more threads on the topic.
My 0.02 cents:
Minimum 3 more spots - Floyd EE, Paskorz and Walker graduating
Maximum 8 (without getting too far fetched) - Floyd and Rudolph EE, one of the Fr. Qbs transfers...my guess Rees, Eifert reinjured/too much pain in back, Paskorz, Walker, Nwankwo, and Nuss do not come back.
The number will be closer to 3, though other unforeseen problems could cause attrition as mentioned...my guess 5 (S, WR, DL/OL, then hold for big fish like Huggins, Rome, Richardson, etc...that may have late decisions.
