User blog:Mr.DannyHancock/Garps strength

Do you guys think that Garp is as strong as Whitebeard. If Garp cornored Gol D. Roger then that means Garp was as strong as him. and if Gol D. Roger tied in a fight with Whitebeard. Doesnt that mean that Garp is also as strong as Whitebeard? But then it makes me wonder why Gol D. Roger was named the pirate king when Whitebeard is just as strong? What do you guys think?
