Very subjective, as some of the best sportsmen are not media friendly and dont come across well in front of the camera. Depends on generation too

1 Lewis hamilton
2 Tiger woods
3 Nigel Mansell
4 Stephen hendry
5 Mark Lawrenson (consistently boring on field and off)

Brendan Rodgers

You call a man who constantly gets 'holes in one' boring? a man who was nearly heated to death by a golf club.

Andy Murray without a shadow of a doubt.

I cannot stand Toffis (I mean TENnis) hence the reason I ain't watched any of it. Strawberry's and cream, a royalty box and a boring crap Scot Tennis player getting his arse run around all over the court by somebody with a bit of go. Every year. Without fail.

All to the tune of "Come on Andy!" sung by a bunch of posh toffs.

Love it.
