Guess the champ by weight class & professional career duration

Stuck with adults but would much prefer the company of the usually more civilized and well-behaved little humans.

Either of those sounds lovely!

No, my lot is drilling math (from basic algebra up through intravenous flow rates), law/ethics, and pharmaceuticals into the heads of healthcare workers to prep them for national cert exams.

 

Yeah, that may've been unclear. Doesn't have to be after.

 

Clarification on the hint:

Just carefully re-read Drew's post that I'd replied to and noticed one important detail. The hint never specified being the last champ with a hundred or more wins. Just that centurions are, nowadays, a dying breed. (Campas remains the most recent, I believe, with nobody looking close to reaching the mark in today's field)

 

I can drop a hint for the feather if agreeable?

 

Honor system, pick just one.

Hint 1:

Gangway, fishies - missile coming through!

or

Hint 2:

Spoiler

You can actually take José Legrá's career bouts total and add that of one Mr. Roy Jones Jr., and this FW still exceeds the number.

 

The very same!

221 career bouts, one more than the sum of Legrá's 144 and RJJ's 76.

 

Alright, time for my swansong. It's been a pleasure, gentlemen, serving as your temporary gamesmaker.

ROUND XV

• Middleweight, 18 years, 14 days
• Light Middleweight, 12 years, 3 months, 17 days

Hint:

Trips to the Well...

 

You not playing? Final round, of the IB epoch anyway.
