Conor McGregor's head coach thinks "Notorious" may have punched himself out against Nate Diaz at UFC 196, which eventually led to a second-round submission loss for the Irishman (see it again here).
Now, one of Conor's closest training partners, Gunnar Nelson, chimes on on his comrade's defeat, saying that he agrees he may have punched himself out because the right strategy wasn't in place to defeat the bigger fighter in the welterweight showdown.
That said, "Gunni" also told Submission Radio he would prefer to have Conor stay put in the smaller weight classes, particularly the lightweight division.
