Arch has a ton of resources and is probably way ahead of where most kids his age would be. Sark is a great coach be he is also getting help from the family members.
Quote from Peyton Manning on a podcast
"And he will, every now and then, text me with a question about a two-minute drill, this is what happened in practice today. And I'm sure as soon as he texts me the question, he regrets it. Because you can't answer a question about a two minute drill with a text back. You have to go to the voice memo. And it can't be just one. So you bang him back with a seven minute voice memo response about the two minute, about what the defense is doing, the plays that you like. You gotta go to your staples. And then you finish it and you're like, I didn't even mention the fact that a defense after a time out will probably come with an exotic blitz. So you better call a max protection coming out of the timeout. And then you finish that one, that's about a six minutes. And then you're like, I totally forgot about the red zone. So three voice memos later...he's probably calling Eli more."
Quote from Eli Manning about a text message.
'Hey, good game. Made some nice plays. Hey, last play, it looks like they rolled a cover two. You try to force an out to a single receiver instead of working the three-receiver concept to the right.'
