Your rush to judgement on all of these players is pretty startling. Also, just because talking head A or talking head B says this guy could have been picked in the 4th or 5th doesn't mean that the player can't become a valid starter. Granted, they spend more time evaluating the players than us on this message board (it is their job), but they're not always right. There is no mathematical formula to say this player will succeed and this player will not. They day I solely base my opinions on what the ESPN or NFL network guys say (especially Dilfer) is the day I stop watching the draft.
Remember when TJ Ward was picked? A lot of people were kind of pissed off and had never heard of him at first either. All that some knew was that he played for Oregon based off of what they had seen in the Rose bowl game with OSU. And that he could have been picked in lower rounds. Of course if the guy can play then who cares what round he's picked in.
But in another sense maybe I can understand why you feel this way. Could it be because this draft is void of a lot of talent that has been in past drafts that we almost take for granted?
