What we learned from Week 2 of NFL pre-season: New Broncos offence looks dangerous

Week 2 of the NFL pre-season is in the books, which means there's just one more tune-up game sitting in-between now and the real thing beginning on Sept. 9.

Through a pair of games, teams are already getting a good sense of what the depth chart will look like, who will handle certain downs, protection schemes and all the nitty gritty bits of football.

But for us, it's a chance to analyze the teams and players from afar. So, here's what we learned about Week 2 of the pre-season:

Getting into his first game since fracturing his ankle late in the divisional-round win against the Buffalo Bills last season, Bo Nix looked like he's ready to rock and roll.

Granted, it was limited action for Nix and the first-team offence, as the third-year man under centre in Denver took the keys for just two drives in his action under new play-caller Davis Webb.

Nix completed 6-of-9 passes for 76 yards in those drives, and there were two plays that really stood out: A 21-yard TD toss to RB RJ Harvey on a wheel route and a 35-yard seed up the middle to a wide open Jaylen Waddle.

A pleasant sight for Broncos fans, the Harvey wheel route wasn't anything new because the two connected on the same play in Denver's win over Houston last season. Still exciting for fans to see, though.

Waddle's grab was his sole one of the game, but a WR creating major separation 20-plus yards down the field is something the Broncos have been severely lacking at the position for nearly a decade.

Already a good unit, Denver is loaded and back healthy. If the small sample size holds true, the Broncos are on track to have one of the more explosive offences in the league.

Rueben Bain Jr. is on a mission to make sure the teams that passed on him regret their decision.

The Tampa Bay Buccaneers rookie made his pro debut on Saturday, and displayed the pass-rush ability that had him in contention for the top pick for a majority of the collegiate season.

Bain Jr.'s name was in headlines leading up to the draft due to media concern over his short arm length.

Was that actually a major factor among NFL front offices? We'll never know for sure. But he did become the first defensive end since 1999 to be selected in the first round while having sub-31-inch arms.

And now Jason Licht and Co. in Tampa are quite happy the University of Miami edge rusher fell to them, and Bain Jr. showed why in Week 2 as highest-graded defender among first-round rookies, per Pro Football Focus .
