Kell's competition 2004-early 2008?

[Fenster]

Carson Jones wasn't the first "good" fighter he faced, he was the first to give Brook a wake up call. Brook badly tired after semi-punching himself out and lost control after his nose was smashed to a bloody pulp, which prevented him from comfortably breathing, hence his attitude and training regime vastly improved, and by all accounts turned into a serious dedicated pro.

As we're playing numbers. Between his first British title shot in 2008 and the first Carson Jones fight in 2011, Brook's 11 opponents combined record was: -

305 wins / 48 losses, 12 losses came from former "world" champion Lovemore N'Dou alone.

The combined record of Errol Spence's last 11 opponents, which covers 2014-to-2017 is: -

246 wins / 36 losses, which includes his last two wins Algieri and Bundu (best opponents).

Brook's opponents win/loss record since Carson Jones 1 reads (last nine bouts): -

268 wins / 20 losses, 9 losses came from Carson Jones alone. Jones was 19-1, 14 KOs in the three years prior to facing Brook, with his only blemish being a disputed split decision (claimed he was robbed).
