Julius shows the attributes that all great RBs must have:
1. Excellent vision - The ability to "see" holes, to know when you can shoot through the line and when to bounce it outside or to cut it back inside. Emmitt was one of the best ever in this area and Julius seems to be just as good.
2. Outstanding balance - The ability to maintain your balance when hit or when cutting. Again, this was one of Emmitt's greatest strengths and JJ's as well. Not as good as Emmitt in this area as he tends to go down fairly easily from ankle tackles but he can improve that over time.
3. Acceleration - The ability to go from zero to 60 in a split second. Barry Sanders, Sayers, and Dorsett had this and Julius has it even more, comparable to Sayers IMO. His acceleration is simply amazing! Lots of guys can see the hole but to be able to hit it and get through it before it closes is rare.
4. Cutting ability - To be able to change direction without losing your balance or slipping is what sets truly great RBs apart from good ones. Gale Sayers was the best I ever saw at this followed closely by Sanders. Julius showed some real "ankle-breakers" in the video, particularly against the Giants. As I said, he has outstanding balance and it shows when he cuts back.
5. Strength - This shows in the player's ability to break tackles or strain for extra yardage. Emmitt was one of the best ever in this area and it showed in his TD record which is 41 (164-123) ahead of 2nd place Marcus Allen. Julius is not as strong as Emmitt was but still shows good strength and determination to gain those extra yards. He does need to work on his "stiff-arm" and spin out of tackles a bit more, but again those are things he can improve over time.
A few comments about what he needs to work on:
1. It seems that he carries the ball in his right hand almost exclusively. This will cost him over time as DCs will look to exploit this and have their players knock the ball out if they know it will always be in his right hand. He needs to learn when to shift it to his left and when not to.
2. Breaking ankle tackles. This is a tough one becasue part of what gives him such excellent balance is that he keeps his feet under him but that also leaves him vulnerable to having them trapped together by a tackler and brought down fairly easily. He needs to learn when to high-step or spread his feet to avoid getting trapped like that.
3. He does a pretty good job of avoiding solid hits but he does take a few of them which will shorten his career. This was something that Emmitt was especially good at. He also needs to work on delivering the blow rather than accepting it, Payton was the best at this one and developing a good "stiff-arm" will do wonders for lengthening his career.
4. Pass receiving. He could be a better receiver both in running his routes and catching the ball. The reports are that he worked on this a lot in the offseason so hopefully he should be much improved in this area. Not that he was horrible but he dropped some easy passes and didn't sell his routes very well.
5. Blocking. Again, they say that he has been working on this during the offseason so hopefully he has improved in this area. He will probably never be near as good as Emmitt was in this area but being good at it will be enough.
Overall, I believe Julius has all the attributes to be a truly great RB in the line of Perkins, Dorsett, and Emmitt. It would be pretty cool to have a 3rd Cowboys RB in the top-10 all-time list and I think he could do it. He certainly has the skills but it remains to be seen if he can stay healthy long enough.
