Kubiak will probably open it up with a line that can get a guy like CJ more than 3.9 yds/att in a SB (or more than ZERO for Hillman) and doesn't give up strip- and other sacks like a cheerleader gives it up on prom night. He'll probably still nurse that big INACCURATE arm along until he has more than half a dozen starts though.
Shit gets OLD, dude: When Manning's in, he limits Kubiaks offense, but when Bossweiler's in KUBIAK limits HIM. Maybe the line's garbage that doesn't give EITHER of them any run support OR protection. Maybe 5 League MVPs>6 career starts. Your boy's got a shot, but if he DOES become a franchise QB (and the odds are against him whether you like it or not) it'll be BECAUSE of Kubiak:
EVERY starting QB he's EVER had—Young, Elway, Griese, Plummer, Schaub, Flacco—made at least ONE Pro Bowl under Kubiak. Two went 3-0 in SBs and into the NFL HoF on the first ballot. The guy WON A PLAYOFF GAME WITH A ROOKIE 5TH ROUNDER, because that was the highest draft pick his idiot owner would let him spend in a desperate attempt to upgrade Schaub before he got them BOTH fired.
Four years, a head coach and a bunch of bum QBs later, that team's best hope for 2016 is: The same 5th round QB Kubiak drafted in 2011. Hell, McNair wouldn't even let Kubiak spend a SEVENTH (i.e. FINAL) round pick on Keenum in 2012; he had to wait till all 32 teams passed 7 times and then snatch the guy up as an UDFA. Now he's the Rams best hope for 2016. Imagine what Kubiak could've found if allowed to draft a QB in the 4th, let alone higher.
Point being, again, IF your boy's a first ballot HoFer it'll be because Kubiak MADE him one, not because he overcame a moronic coach "holding him back." The reality is new NFL head coaches come in on a timer: 3-4 (MAYBE 5) years to get to a SB or they're GONE, and even getting there only buys them an extra year or two to win it. Well, Kubiak won it his FIRST year; how much time do you think THAT bought? Even before considering he was the GMs rookie camp roommate, backup through 3 SB losses, and OC for a pair of SBs wins. There's another thing all new coaches do: Find "their" QB. If that's Oz, great, but if not, we and he will move on separately.
Now, let's all get back to savoring our Super Bowl win. It takes a mountain of skill AND a heavy dollop of luck to get one, and they're STILL rare: Don't spoil this one.
