I would fancy Lyle to be too dogged for Buster and to eventually drag buster into a bit of trench warfare, which, as in the Tucker could see Busters resolve evaporate. Against Tyson, Buster, apart from the shot that floored him, and he looked like he was thinking of staying down, didnt really get dragged into any sustained suffering from Tyson, he was able to control him from long range and with Clinches up close, it wasnt long before Tyson was looking a bit confused by this resistance, and Buster fed off It, But Lyle will catch Buster with his Jab from Longer range, Lyle did have some good movement for a big man, slipping off to the side quite well, We know Lyle, as displayed from the Foreman and Shavers fights has the resolve to pick himself up and keep going, if he does that with Buster i think Buster's resovely will eventually melt, i know that Jimmy Young Outboxed Lyle twice, But Jimmy did have resolve, he showed it against Foreman and Norton, I think Buster was a very good fighter with plenty of natural boxing talent, but what drives it is mental fortitude, and i think Buster was a good "On Top" fighter only, give him advercity to overcome and he will start to waiver. It might look like Lyles fight with Bugner, if Buster looks to Jab and Grab, if he commits to Victory i can see Lyle Catching him and being too determined and Buster falling apart for a last third stoppage win for Lyle, Putting it all together, Buster may be more naturally talented then Lyle, But Big Ron brings that Fighters Heart and Mindset.
