There are lot of small things to notice during a football practice.
Obviously the big things stand out: touchdowns, hurdles, interceptions, you get the idea. We can learn a lot from practice, we can discern a great amount of information about each player and sequence.
When watching Cole Beasley practice out in Oxnard I noticed something unique to him when looking at all of the wide receivers... he practices without gloves.
Cole is the only Cowboys wide receiver who practices without gloves. Some players take them off for particular drills, but Cole goes glove-less all of the time.
