This could be one of those "announcements" and the guy is actually walking on. If this guy is smart enough to get into Harvard, and since his Dad is high up in the athletic dept., I bet we can find a way to get him on the team without burning a scholarship.
Personally, I have nothing wrong with good will towards our own alumni. EVERY school does this. How many players has Ole Miss had " whose Dad played with Archie?" And how many players have they had related to Barney Poole and Charley Conerly? It's not just Ole Miss, look at Bama. They have a ton of guys whos Dad played for the Bear, or heck their Mom was a cheerleader.
Looking at McKenzie, it's not like he's a 5'10" 150 pound DE. He's 6'3" and he's listed at 230. He could legitimately develop into a solid player at a couple of positions. A guy like Hollingsworth was listed at something like 5'11" 180 at QB. That's a big difference to me. If Hollingsworth came, he would be continuing our tradition of lollipop guild QB's.
Also think about this- remember when we wouldn't let John Grisham's kid on the baseball team? Well, he ends up at Virginia, and now they are getting the benefit. Sometimes not bringing in a legacy can end up biting you in the ***.
