The Buffalo Bills had a tremendous draft class and their undrafted free agent class has also received their fair share of praise.
Zimmer played at D-II school Ferris State and put up huge numbers in the last three seasons. In 2015, Zimmer led his team in four categories: tackles (81), tackles for loss (26), sacks (13), and forced fumbles (4) per mlive.com. Here's a look at Zimmer's last three seasons with the Bulldogs:
In all, Zimmer has recorded 214 tackles, 48.5 TFL, 26 sacks, 14 passes defensed, and nine forced fumbles in the last three seasons. It's safe to say that he's been very productive with the Bulldogs.
The stats alone are more than productive, but have we mentioned that Zimmer is an absolute freak of nature in terms of his athleticism? Zimmer is 6'2" and weighs 302 pounds. You'd never guess this after looking at the eye-popping numbers that Zimmer had at the Houston Regional Combine and University of Michigan pro day.
At 302 pounds, Zimmer ran a 4.85 40-yard dash according to Gil Brandt. On the bench press, Zimmer recorded 44-reps of 225 pounds. He also posted a vertical of 33.5 inches, a broad jump of 9-feet-9-inches, and a three-cone drill time of 7.01. These are staggering numbers for a man of Zimmer's size.
Kent Platte, a writer who created the RAS, Relative Athletic Score, showed where Zimmer ranked against first round defensive tackles from 2005-2015.
Zimmer finished with a higher score than any former first round defensive tackle over that span of time.
The production on the field at Ferris State was certainly there for Zimmer and his athleticism certainly cannot be questioned. Zimmer is one undrafted free agent that all Bills fans should be following closely now and at training camp.
