Why people need to consider Marquez a threat for PBF

[Manuel "Chubby" Medina]

Can Marquez carry his speed and power at 144? Will he be able to take a good punch from Mayweather? Is he smarter than Floyd?

Tough fight for Marquez. But the pressure is on Floyd.

When he fought Casa i saw him carry his power when he decked Casamayor and also Diaz who both never been decked before.
As for speed in the Casa fight Marquez looked a lil slower than usual but in the Diaz fight he look the same as ever.
But at 144 who knows? we'll never see until fight night.
