I'm reminded of Allen Iverson's rant about "practice." I'll wait until we actually see him on the field before I come to any conclusions.
One of the things that will be interesting is if he plays in the preseason, and if so, how much. One of the things that IMO contributed to his poor season last year was that RW didn't play a single snap in the preseason, very unusual and perhaps unprecedented for a quarterback who is playing for a new team. IMO it showed up in their first game against us as their offense was very unorganized.
I agree with others that have commented about Russell's social media presence. All he's doing is embarrassing himself, and he doesn't seem to realize it, tone deaf.
