Switcheroo? Yes, I'm asking when has a guy gotten some playing time and been so impressive, he moves up the depth chart and starts the following week. There have been chances at it at many positions. Jones being replaced by Burnett in the hybrid spot is a veteran taking an ineffective rookie out, so not really what I was looking for.
Even from year to year, seems like once a starter, you are locked in until you are not resigned, traded or injured. Maybe this year we will see Jackson or Alexander change that.
Another possible example is Byron Bell getting the start in Week 5, taking all snaps at RG. While McCray was on the injury report he was active. We'll see where that goes.
The OLB situation is interesting as well. Perry was questionable in week 1 with an ankle injury. Since then he has not appeared on the game day injury report. His snap counts have been, in order, 53%, 55%, 62%, 57% and 35 snaps in week 5 (57% on an estimated 62 plays).
Gilbert's snap counts are 53%, 47%, 39%, 43% and 31 snaps in week 5 (50% on an estimated 62 plays).
Perry is high priced and expected to be a 3-down player, say a 70+% snap count. Yet despite being off the injury report after week 1, his snap count has not gone up appreciably while Gilbert has continued to get a significant number of snaps at Perry's expense. So, jumping up on the depth chart can be a black and white way of thinking about it when situationally there are shades of gray.
CB is an interesting situation if all of the top 5 are healthy at the same time. The snap counts during week 1 were:
Williams 100%
King 100%
Alexander 70%
Jackson 66%
That indicates Pettine played 4-corner dime on 36% of the snaps against a Bears team better know for their run game than Trubisky as a threat, compounded by the Bears holding a 17-0 halftime lead where it would be expected they would want to run and control the clock in the second half. This may indicate a preference for a dime-heavy approach when all hands are on deck though Burks' absence may have been a factor. We won't have a better picture unless and until all 4 are healthy at the same time.
In any case, this is an instance of where who starts is not necessarily an indication of how much the other guys play. Those Alexander/Jackson snaps are pretty significant for their first NFL games. And it should be noted that Williams did not play on the perimeter for all snaps, taking some in the slot, indicating a preference to play matchups. King stays fixed at LCB when he plays. That may be a function of simplification or the fact he's probably the best run defender of the bunch on the side where opponents best run blockers typically reside, or a little of both.
Now Breeland is thrown into the mix. The fact he went unsigned that long and then signed this modest contract with the Packers raises questions. For the time being, that looks like a depth move, especially given the injury situation at the time he was signed and which has continued.
I don't see that changing but it seems King has yet to take a healthy NFL snap so that projection many not be tested. In any event, the King injuries get the rookies more snaps and and opportunity to make their case.
