I think Jennings was a bit too loose vs Tupou, but after the knockdown he turned it on and finished with class. Tupou has some pop too. I think Jennings has grown since then a bit but when we start thinking about Jennings vs Mansour I think the major problems for Mansour would be Jennings' reach, his athletic ability, his punches are delivered quickly and straight, and he's got very good footwork. Mansour is kind of a poor man's post prison Tyson, his footwork gives him a good solid base for power, but he's a little plodding in his movement. Amir's best punches are his right hook and left cross...the hook is a bit loopy and lands behind the head/doesn't land clean but his left cross is a good punch but it's something a guy who is not leaning in and circling the wrong way can easily avoid. His head movement wanes after a few rounds as is typical for a pressure fighter and he's trying to be a pressure fighter which he has done a great job of thus far but here's what will happen to him: He'll get horribly outboxed (Jennings), he'll meet a stronger tougher pressure fighter(Ruiz Jr), or he'll catch a huge shot and be absolutely shattered to bits (Wilder).

Mansour might could have done something at age 23, but pressure fighters have a time limit...tick'tock, tick'tock, he's 41 and soon to be a pumpkin
