The way I'm looking at the draft is that you need to get two valuable (ie. starting or major contributor within two years) assets per season. I don't think a person can linger on the where they were drafted part.
2014- Shazier, Tuitt Look like at least one of them will be a very good starter add in Bryant and you have almost two sure starting/ contributing talents. Maybe three (good draft)
2013- Jones, Bell, Wheton, Williams, Thomas. Lots of question marks here. If Bell stays out of trouble, stays healthy and signs a second contract here he is an absolute steal. He would be first round, probably upper first round on anyone's do over draft board. Jones looks like a bust, but with the low cost of recent first rounders you just have to look at it like we got Bell as a first rounder and Jones ia second round bust. Wheton and Williams look like good bacjkups with maybe one of them being a solid starter. Thomas???? On the surface it looks like a bad draft with the Jones bust, but could still go either way. Bell's career with the steelers will define it.
2012- Decastro, Adams, Spence, Beachum Decastro is a solid guard with pro bowl potential. Hard to be against Spence, but he is probably a good backup. Beechum could be the only saving grace of an otherwise poor draft.
2011- Cameron Heyward, Cortez Allen, Gilbert. Hard to see this one as anything but a disappointment. Heyward is a really good player, but the wait was long for him to get good and he goes through spells where he disappears. He isn't nearly enough to make up for the stench of the rest. I'm hoping Allen might get his confidence back and become serviceable. Worst draft of the period.
2010- Pouncey, Brown, Sanders, Worilds. Pouncey has received accolades, Brown is top three to five at his position, Brown and Sanders were sought after FA's. Hard to say much bad about that draft.
You would have to go through every single draft board, but my guess is the Steelers draft success over the past 5 years is about industry standard. They have produced about two starters to stars every year. They have misses in the top of the draft and big steals later on. Its about what you'd expect.
