Can't find anything on others pursuing Kemp and Giest but some of the other guys at the point they committed:
Willie Jackson: Other schools on Jackson’s radar included Boston College, Wichita State, Temple and locals Cleveland State and Akron.

Mitchell Smith: For a long time it appeared that Smith was likely to land at Arkansas, but the Hogs backburner'd him a bit and it allowed other programs to sneak in. Currently Smith lists Mizzou, Creighton, TCU, Wichita State and Arkansas as his leaders.

Vanleer: who had such suitors as Evansville, Lehigh, and Wofford along with Missouri State and SEMO when he accepted Kim Anderson’s scholarship offer.
