I was just watching some 2017 highlights and noticed him out running angles. This was most evident in the MSU game where he scored on that 80+ yard run and blew by the entire secondary.
This is stark contrast to the previous year where I saw a couple of times of him getting tackled from behind.
If Dobbins is thunder, Weber is definitely lightening. I would be willing to bet that Weber will run in the 4.4s in next years draft. Kid looks so much faster than he did in 2016.
