Jason Pierre Paul only had 4.5 sacks his rookie year, and didn't record a single one until WEEK 8.
Would you all be satisfied if it took Irvin a year to turn into a player like that? Obviously they're slightly different roles, but both were / are EXTREMELY gifted athletes who were super raw coming out of college. Give the guy some time. I agree it's been frustrating but I'm willing to bank on PC & JS knowing what the hell they are doing (on the defensive side, at least).
And, not to be a total downer, but as clear as it seemed during the preseason that the Hawks "window" was now open, our play in week 1, and even more importantly the 49ers play tells me that we're not QUITE there yet. That's not to say I don't think we can make the playoffs and maybe make some noise, but I'm not ready to declare full on divisional dominance for the next 5-10 years, like maybe it seemed after the preseason.
So yes, IMO, the Hawks can afford for Irvin to be a project.
