I don't think he could get away with that type of defense (fronting/ball denial) over a series though since they'll adjust and Gasol might grow a set too and actually fight for better position.
Of course Pau can fight for better position but you have to remember LeBron also has a strength advantage of Pau. When they matchup, really the only edge Pau has over LeBron is his size, Pau's strategy would have to be to use his size as an advantage over LeBron to be able to create himself some space to get open and get off good looks.
Boston is probably the only challenge for the Heat. Heat could probably easily beat everyone else. So many ppl forget that Bosh was basically out the whole series with Indy and Boston. Hell I said Boston but no way is KG having that kind of run he had in a longer season and if Pierce doesnt give them at least 18 game they could be in trouble. Rondo is prob the best passer in the NBA so he could prob help them even if there main players talents are diminishing.
Forgot bout the Nets. Always thought Joe Johnson was great but last couple years I see he really cant step up when he needs to like other superstars.
Most of the intelligence community doesn't believe he exists, the ones that do call him theWinter Soldier
