I think a better question is how many prospects (that we were considering and didn't pick) went on to become pro bowlers? hindsight doesn't count, and Pierce Upshaw and Osemele were critical pieces in our Super Bowl win. Harrison Smith would be nice now but I prefer the championship.
2014 gave us three starters, 4 if you include Jensen. Based on the visits tracker and rumored targets we were never going to come close to nailing the first two rounds. We did OK in what was a God awful draft class.
2015 there has been nobody of note from our first pick onwards.
