Well, sadly we have no one going on a daily basis as I usually do and are forced to get our info from other sources.
To me the most interesting 2 are that Alex Collins has slimmed down and that is helping him have more impact. That seems to be part of a trend as a number of players have had body make overs it seems to get them more appropriate bodies for what they need: Fant has gained 27 pounds out at left tackle, Russell Wilson lost 15 pounds to get back to his speedy self we saw back in 2012 - abandoning the idea that "thicker" would help him endure hits, Lawler gained 15 to 20 pounds to try to look like an NFL receiver not a high school JV player with NFL hands. Interested to see what dividends all this pays.
The other interesting take away for me was that Kasem Williams is making a case for himself. Last year I thought he had a shot to make the regular season roster til he got hurt. I sort of feel like his window is closed.. if he was special we would know it by now and meanwhile every year there is a crop of borderline players.. but if he has upped his game and stays healthy he has potential.
Will add more about what we learned from Day 2 as, well, I learn. Brock and Salk should have something to say!
