Tony's crazy to tangle with Mike! (5)
I believe the answer is:
tyson
'tangle with mike' is the definition.
I can't tell whether this definition defines the answer.
'tony's crazy' is the wordplay.
'crazy' is an anagram indicator.
'tonys' is an anagram of 'TYSON'.
'to' is the link.
Can you help me to learn more?
(Other definitions for tyson that I've seen before include "26 4 [RING MASTER]" , "Mike ..., former US prizefighter" , "Youngest ever undisputed world heavyweight boxing champion, b, 1966" , "US world heavyweight boxing champion, b.1966 -- English fast bowler, d. 2015" , "Mike --, US boxer" .)
