NE plays a hybrid man/zone blocking scheme, NE OL have to be able to drive block on one play, and be quick enough to get to their zone assignment on the next. NE favors kids who are dancing bears in pass protection who quickly transition to stampeding wildebeest in front of running backs, receivers, and tight ends for screens. NE OL don't just block on the second level against linebackers between the tackles, they have to play in space. Agile, mobile, hostile - it's a job requirement.
I like watching O-line play, but I'm not the most gifted analyst when it comes to breaking down a player's skillset on my TV (with all those helpful camera shots of ankles and helmets and crowds). To compensate I use a blend of my lying eyes, NFL Draft Scout profiles, and some specific Combine/Pro-Day drill numbers.
Historically, NE seems to favor "starters" who can generate enough leg drive to push 300 lbs 30" or more in a vertical jump. Mankins 31.5", Kaczur 31.5", Vollmer 36.5". I have no jump data for Light (though as a converted TE he probably skyed okay too), Koppen had 28.5" but he was also a fifth round pick. Neal never went through the Combine or a Pro-Day, but he was a world class wrestler and anyone watching him move around a football field had little doubt about him. That 30" benchmark seems pretty solid; they've had successful reserves who didn't get that high - Hochstein reached 26.5" (5th round via Tampa), Connolly 28.5" (undrafted via JAX) - but "starter" is the operative word when assessing if a kid has the type of leg drive NE seems to prefer.
The next thing which stands out about NE starters is agility numbers. 4.5 second short shuttles and 7.5 second 3-cone drills or better seems to be preferred if they are going to take a kid high. Mankins 4.5/7.5, Light 4.5/7.3, Vollmer 4.5/7.5. Klemm is the other OL drafted in the top two rounds, I have no data on him, but he was switching from OT to TE and back while at Hawaii, so I'd say he was athletic enough. The next two highest drafted OL, I have no data on Kenyatta Jones (FWIW he was a basketball player for USF which suggests good foot speed) and Kaczur has 4.8/7.7 for his agility.
So, by the numbers:
-- Ty Smith: 4.7/7.5, 29" (fresh off knee rehab)
-- Tony Castonzo: 4.4/7.3, 29.5"
-- Gabe Carimi: ??/??, 31.5"
-- Nate Solder: 4.3/7.4, 32"
-- Derek Sherrod: 4.6/7.4, 28"
-- Jim Carpenter: 4.8/7.6, 28.5"
-- Ben Ijalana: 4.7/7.8, 25.5" (fresh off sports hernia surgery)
-- Dan Watkins: 4.6/7.6, 26"
With the exception of Ty Smith, these are all college left tackles. Ijalana and Watkins are projected inside to guard by most draftniks, but Watkins has been discussed as a good right tackle and Ijalana is still considered by some to be worth consideration at left tackle in the NFL.
By the numbers:
-- Smith is borderline with mitigating injury factors and the fact he just packed on 20+ lbs and is still growing into his new body.
-- Castonzo is a shade below desirable in one measure.
-- Carimi's lack of agility numbers is troubling because that's one area he gets negative reviews on from film.
-- Solder meets the mark.
-- Sherrod is probably a third rounder.
-- Carpenter is probably a fourth rounder.
-- Ijalana is definitely day three with those numbers coming from a small school, injury or no.
-- Watkins is a day three pick.
By my lying eyes watching a TV screen:
-- Smith is a big question mark, I watched USC to check him out and he did nothing one way or another while I was watching. (The left tackle Kalil was a stud.)
-- Castonzo is meh. He's there, he's playing, he's keeping the QB clean and he's hitting someone, but I don't see the fire or nasty Scar loves.
-- Carimi is a run blocking beast, pass protection is okay. If he was an inch shorter I'd move him inside (for a hawg team like Philly or Dallas or Pittsburgh - not NE's stampeding wildebeest brigade).
-- Solder, he's raw, but he moved people, looks like a young Vollmer on my TV.
-- Sherrod is okay, like Castonzo, okay.
-- Carpenter, I thought he would make a good NE guard the first time I saw him and nothing since has changed that.
-- Ijalana, one game, he seemed to have it all, but it was an FCS semi-final, so good competition, but not SEC.
-- Watkins, loved him.
Is Smith a franchise left tackle as Manx asks? Probably, I'm just not sure that franchise is NE, but he did take a visit to Gillette and Scar was at his Pro-Day.
If I'm ranking them:
1. Solder
2. ??? probably Jah Reid, move Vollmer to LT and see if this kid can beat Kaczur and LeVoir for RT.[/B
]EDIT: One other factor to consider is the coaching relationship connection.
-- Ty Smith's O-line coach, was the O-line coach for the 2007 and 2008 Oakland Raiders.
-- Castonzo, BC and Scar have a long relationship.
-- Carimi, none I can see.
-- Solder's O-line coach transitioned Tom Ashworth from TE to LT; NE's new asst. S&C coach was the asst. S&C coach at Colorado last season, and worked with Mankins and Wendell at Fresno State.
-- Sherrod, the O-line coach was at Florida and coached Hernandez.
-- Carpenter, BB and Saban. His O-line coach retired, he was an OL coach and OC in the NFL for years so I'm sure Scar and BB new him.
-- Ijalana, his O-line coach has been there 12 years, we know NE likes their safeties.
-- Watkins, his O-line coach worked with Vollmer at Houston.
