Re: Tall, lanky, output fighters...
The deal with Pavlik and Margarito is that they just aren't good BOXERS. They are good prize fighters, but as 100% pure boxers they are utter crap....well maybe not that bad but they are well below average.
Pavlik used his size and power (much like a middleweight version of Cris Arreola) to overwhelm his opponent, Margarito is like Glenn Johnson but without the defense. The trouble for these guys is not everyone allows themselves just to be overwhelmed and even if you are in the 99th percentile of height/reach/power/etc in your division there is ALWAYS someone out there who is slicker, faster, and has better defense or simply is a smarter fighter.
A great boxer is usually going to beat a great puncher and that's just the facts.
As a fighter the best advice is to prepare to go the distance and always ALWAYS have a backup plan. Sometimes big punchers have got to box because they are in with another big puncher...sometimes good boxers have to land hard punches to keep off the pressure from the other fighter.
Pavlik and Margarito just don't have a plan B
