If I'm not mistaken, one of the knocks against Russell Wilson QB was that he was 25 when drafted, (he played baseball). He went early in the second round. Look how that turned out.
If you read the Margus Hunt thread, there is a comparison to Michael Carter, a great 49er lineman who won a silver medal in shotput at the Olympics. As a result, he too was older when drafted, and needed training to become a starter.
Margus Hunt is a medalist in discus and shotput. As a character guy, he is a champion already. Like Michael Carter, he already has great upper body strength. And without a full repertoire of moves, already has a body of game footage that shows penetration and the potential to dominate.
The 49ers are a perfect situation for Hunt. We have 2 good DEs, and are looking for a third to spell the starters this year. Hunt can start as a rotational player this year, learning his trade from Cowboy and Ray Mac.
Lastly, when you have a championship team, it is difficult to draft a guy who will step in from day one and make an immediate impact, because the 49ers are already loaded with talent. None of our last two drafts came in as a starter: 2012: AJ Jenkins, LaMichael James, Joe Looney; and 2011, Aldon Smith, Colin Kaepernick, Chris Culiver, and Kendall Hunter. So the 49ers have the luxury to groom their draft players.
If a superior talent falls to the end of round one, because of his age and lack of football experience, that is exactly who you want to draft.
