I don't watch much of the Razor Pigs either S Dub One! I always found them to be a boring team to watch personally. I remember both of my High School coaches at Tucker High School in Atlanta, Georgia were both from Arkansas and they both loved the Razor Pigs. We had a mean ground game featuring Patrick Pass as our tailback. Those were fun times!
I got distracted and had to come back to him, but I just saw a return. By the end of 2015, he seemed a little big and boxy, more of a bruiser than a shaker, but still showed some wiggle. Maybe he was hurt, or just worn down from his 2,000 yard season. I've been watching whatever I can find on him, even opponent stuff, because he only has three cut-ups on draftbreakdown.com right now.
I compared him to Lynch earlier, but now I'm thinking he has some Le'Veon Bell to him. It's a very unconventional running style -- too upright, a little hesitant approaching the line, etc. -- but it works for him, just like it works for Bell in the NFL. I don't know if Collins has the burst to still get to the second level in the pros, but in 2014, he looked faster than in 2015, showing a 6th gear.
If I'm right and he was heavy and/or hurt by that K-State bowl game, and he's in better shape for the Combine, he might turn some heads.
It's a good thing that HC Bret Bielema has such tremendous blocking talent & RB talent at Arkansas because the #1 knock against him at UW-Madison was his failure to never know when to take a time out on the sidelines. His clock management skills were just atrocious. When you have solid talent on the ground, you can get a pass on adjustment liabilities.
I don't watch a ton of Razorbacks ball so I can't say with any great deal of authority whether Bret has improved in the timeout area or not.
