I watched pretty much every game of Harrison Smith's career, and I gotta say, I have no idea why people think he is good.
I literally watched every minute of every game of Smith's career and broke down film of about 70% of those games and Smith is a very, very solid player.
He is fast (4.5 range in the 40 and it shows on the field), athletic (34 inch vertical and 4.12 short shuttle time - outstanding) and he is big at 6'2" 215. Also 19 reps on the bench press, outstanding for a safety.
He's not Ed Reed, but he's rangy, spectacular against the run, a much bigger body who can cover anyone including tight ends and slot receivers.
If you've watched all of his games, you would know he makes insanell athletic plays on the ball in the air and on the ball carrier. He has a knack for avoiding blockers and has the athletic ability to makes plays while doing so.
As I said, he isn't going to pick off 5-7 passes a season, but he'll have 3 or 4 and will have over 100 tackles every year. Sorry, but your assessment is wrong.
Can also play up to the LOS in the nickle if necessary, can also play SS or FS if needed. He's also a solid blitzer who can get to the QB if asked.
One more thing: He was the field general of the ND defense this year and with Manti Te'O battling knee injuries all season, he was arguably the best player on the field at any given time. He's also extremely durable and tough... He was asked to play more within himself this year and in the type of defense Notre Dame likes to run, he was not asked to roam free in the deep part of the field very much, that is the reason he had no interceptions. With the talent in the ND front 7, they didn't need Smith to be a big time playmaker, they needed him to protect against the big play and dominate the run game, which he did extremely well.
Smith made a lot more plays on the ball in 2010 than he did in 2011, that was mostly by design.
No offense to you, I'm not trying to be confrontational, but trust me I am an obsessive Notre Dame fan. I also don't overrate ND's players. The Notre Dame secondary was average and had very little depth, they needed Smith's leadership and intelligence and he came through big time all year. Zeke Motta, the safety who played the most opposite Smith, has a lot of weaknesses and is really a 4-3 OLB playing safety in a 3-4, so Smith had to watch what he was doing a lot of the time.
Also look for Smith's replacement - Jamoris Slaughter - to get a lot of looks in next year's draft.
