He really needs to engage Mike in the beginning to really test Tyson if he has that power, or his age really caught up with him. Jake though is also known to have a gas problem as he usually gets tired in the middle rounds. And with that added muscle on him as he needs to go up to the heavyweight, maybe it could also have an effect on his body as the fight goes in the distance.
I doubt if Jake is afraid of Tyson. He's 27 years young. He's active, just had his previous fight 4 months ago. This bout is his own making. Tyson, on the other hand, is about to claim is senior citizen ID. So, Jake won't be running all throughout the fight. He won't be unnecessarily catching Mike's powerful shots, though. But if such occasion arises, I think Jake can absorb whatever is left with Mike's power.
I'm not expecting much from this fight, anyway. Jake's the director of this one. Despite his blabber, he respects Mike and is very much aware of his age. Mike, on the other hand, has to do the job creating hype. In the end, it might just be jabs and clinches.
