There were plenty of plays where pass rushers were getting in unblocked or hardly blocked on their way to the QB. Ereck Flowers and Jesse Davis in particular were pretty bad in pass pro. The injury to Solomon Kindley hurt.
Sure, we could break down the 40 odd drop backs and are likely to find a few (far from plenty) where the blocker was beaten badly but we’ll find more (plenty) where Tua was standing there looking, looking and ultimately no line can block a rush for ever. We’ve talked here in previous weeks, even the winning ones, how our WRs don’t get separation, more often not getting open at all. I think that problem is a lot bigger than any fault of a rookie or two on the o-line.
It’s simple. Tua doesn’t want to force the ball, risking TOs, so he holds on to the ball far too long waiting for this bunch to get open. Add Denver’s preparation that smothered the kid with mis-reads and you have the sacks and pressures.
Two of the sacks were a direct result of offensive linemen whiffing on blocks or completely missing blocks. In fact, the commentators highlighted how the Broncos were running simple stunts to confuse the Dolphins offensive line. This created several instances where a pass rusher was actually getting into the backfield unblocked. The Broncos were able to get pressure with 4. So let's not try to downplay the issues upfront.
The other issue, wide receivers not creating separation, is completely valid. One thing I do not have a concern with from Tua is his ability to scan through a defense and find the open guy. But with these receivers, I agree there isn't always going to be an open guy. Fitz made a living on contested throws to DeVante Parker. Tua is an anticipation throw guy.
