In the 2021 draft, Collins and Parsons were flip flopping between #1 and #2 as far as LBers were concerned. Some ranked Collins first and others Parsons. In the end they were pretty much 1A and 1B. Their abilities for the most part were considered pretty even, in other words you couldn't go wrong with either one as both were considered an immediate starter on your defense. Now a year later and one season under the belt we see that Parsons not only started but was a significant contributor to the Dallas defense while Collins wasted away on the bench. I completely understand why some people are wondering if this was another misread by Keim and are questioning if Collins is going to be anything other than a mediocre starter.
I know some are going to blame Vance and his complex defense for Collins not getting on the field, however as the season wore on one I think rightfully one would think that Collins would pick up the system and start gaining playing time. Repetitions in practice and studying to better understand his role and the expectations of his position. That didn't happen, Collins didn't see any real uptick in playing time even into the final 3-4 weeks of the season other than due to injuries. It's no wonder why people are questioning him and his ability to take over the Hicks role which by the way also means calling the defense for every snap.
