So to further a discussion going on in Quinn Carol's thread about inside vs outside guys I wanted to post what I'm looking for in prospects in that regard. I'll never be confused with a professional scout but here it is.
Most people who know anything about Oline is that tackles tend to be tall, rangy guys, but there's much more to it than that. The big thing I look for is in the feet. The most indispensable ability for a tackle, left or right, is being able to counter an outside speed rush. If you can't do that, you're not playing tackle. What I tend to look for is in the feet. Elite left tackles almost glide despite the naturally wonky kick-step to the outside while mirroring the speed rush. Here's a clip of our very own Ronnie Stanley doing this (Time: 4:56):

Then on the flip side, you have guys that have heavy feet, that an explosive speed rush will blow right by. My clearest example of this at ND is Steve Elmer. Guy had all the hype coming out of high school, and had projected as a tackle with his measurable. When I looked at the tape however, in the limited pass-blocking reps it looked like he was holding in a s*hit. This rep at 39 seconds shows this:

Turned out to be a decent starter for us at guard but never became the tackle a lot of people thought.
I've seen very good feet from Patterson from last class and Olmstead from this class, but I have to make note of Kristofic as far as his potential at tackle. While he may be the least ready of the big OL recruits of the last two classes (biggest part of that is bulking up), but he has the traits for what I'm looking for in an NFL left tackle. His tape is stacked with elite pass blocking reps but my favorite is at 3:16 on his Junior highlights. I can't seem to embed from a particular time from the Hudl video but the link to it is here:
