"It's a flat out lie to say that Mahomes didn't have to be coached up or developed. If Mahomes was NFL ready than you claim then there would be no reason to sit him." - Jungle
During that year that Alex Smith played, reports were coming out of practice that Mahomes was LIGHTING IT UP. Making insane throws. Leading the offense. The defense was literally struggling to contain him - the backup!
One article said that "Alex Smith is on notice" because reports were that Mahomes was playing better that Smith in his first training camp ever.
This was in the PRE-SEASON of his FIRST YEAR.
Fansided said in one of it's articles in his ROOKIE season that "Fans of the Kansas City Chiefs have been dreaming of having a quarterback like rookie Patrick Mahomes for decades."
Long story short: There were reports out of Training Camp in his rookie season that he was torching the #1 defense. Then there were reports out of practice during his rookie reason that he was making it hard for the #1 defense to even practice because he was beating them repeatedly.
He did NOT need to sit.
He was great from day 1.
Andy Reid was loyal to Alex Smith. That is all.
