There has been a couple video snippets (Facebook and Twitter) and article quotes but it's seems most are stating that it's night and day from the previous regime. Especially, Keith Belton has created a conditioning environment that's rife with motivation, energy and comeraderie. Go to UNLV Football Twitter feed and Facebook page to see some info. I'll try to post a couple.
I haven't been to any practices and only gather my info from social media and articles so I'm sure some people closer to the program can comment.
