With due respect to Mr.Richards , who did a great job at guest hosting , when replacing the G.O.A.T. host of Jeopardy , who better than the G.O.A.T. contestant ? Alex knew and respected Ken Jennings , and Ken felt the same towards Mr.Trebek a hundred fold . Ken knows first hand how to put contestants at ease , his banter with them at the beginning of the show goes well .Along with millions of others , I've watched the show for many years , and though it's just my opinion , it seems to be a no-brainer , Ken Jennings is the only replacement for Alex Trebek !
