F*ck, you people never stop with this do you?
Why do you always, always think the young guys who "flash" are a better bet on the field? Doesn't it strike you as odd that every single coaching staff chooses to play mostly older guys? Isn't it possible that in practice it becomes clear that the more experienced guys make fewer mistakes and are better at knowing where they should be? Isn't it possible that the guys who get paid to live and breathe football have a better sense of who to put in the game?
Try this. Your QB struggles and you scream that the FR on the bench has so much upside, why not get him in the game? Cool, coach benches the starter and puts the kid in. He has a rocky season, gets sacked a lot and throws as many INTs as TD. The following year, it's more of the same and you scream that this guy has been ruined by playing too early and what the team really needs is to put in the FR who's on the bench. And guess how that goes?
Final question...what's your explanation for the fact two completely different staffs have put Ivey on the field repeatedly? Sure, Manny sucked, but can't Mario see your point? Doesn't he at least know how smart and right you are?
