I think the only possible drawback is he turns 64 in February. I guess the question is do you make the new host someone of that age or do you go younger?
Norm MacDonald as Turd Ferguson is clearly the correct answer. Norm is apparently legit very smart too, if his Millionaire appearance is any indicator.
I like LeVar Burton and it seems like he's a fine choice for replacement but I don't get the "IT HAS to BE LEVAR BURTON" sentiment I'm seeing in my Facebook feed.
