Gregor Clegane other-wise known as The Mountain That Rides, was nearly signed by the Indianapolis Colts in 2013; the older brother of Sandor 'The Hound' Clegane is feared throughout Westeros for good reason.
A massive and fearsome warrior with a penchant for extreme violence, The Mountain probably attracted attention from Colts owner Jim Irsay after raiding the Riverlands on orders from his liege lord Tywin Lannister.
Off/Def Lineman,so many 6-3 to 6-7..320-365 lbs/Big,Physical and Nasty! Speaking of size/strength..GM Grig's just might sign "The Icelander"

Hafthor Bjornsson plays the iconic figure and was a potential target for the Colts roster because of his enormous size. He has also featured in the Worlds Strongest Man Competition, he stands at 6’9”, and weighs 419-pounds.
Here he is making Cersei Lannister look like a sexier Tyrion
Knee injuries have prevented Bjornsson - who used to play basketball - from pursuing contact sports, which is a huge shame, we would love to have seen The Mountain pillaging his way through the NFL.
Unfortunately the only people The Mountain will be able to pillage are thousands upon thousands of defenceless women and children.
