While I agree with this to an extent, there is no way you can rely 95% on on-field play and essentially ignore measurables. There are some very key measurements that correlate extremely strongly with success at the next level. For instance, if you're drafting an edge rusher 3 cone times are extremely important. There was a study done a couple years back and it was about 85% of the top 15 or 20 edge rushers in the league had a 3 cone time under 7.10. So there is definitely a good reason for having certain measurable cutoffs at key positions, especially for first or second round picks. There's also just certain guys who have the baseline athleticism to let their other skills dominate in college, but they then fall below that baseline athleticism requirement in the NFL, so you can't just go off film. Not to mention you'd miss out on a ton of high-ceiling prospects if you only go off of film.
Agree with this. His size/wingspan may keep him from being a dominant LT in the NFL, but he still has a ceiling of being a top 5-10 LT in the NFL, which is extremely valuable. And his floor is very high because he can move inside to G if OT isn't working and still become a Pro Bowl G, a la Cosmi. I really can't see him falling outside the top 15 in this draft, unless he's bottom 5 or 10 percentile for some of the size/reach measurements.
