After an impressive first quarter, Glennon's flashes dimmed. He was only able to lead the Bucs to a pedestrian 10 points in the team's 13-10 loss. While Schiano still appears upbeat about his hand-picked rookie quarterback, Glennon will need to build off his first career loss if he hopes to be the franchise's quarterback of the future.

As an NFL Draft prospect last year, Glennon was all over draft boards. On one hand, teams loved his size, velocity and ability to stretch defenses vertically. On the other, his lack of foot speed and poor decision-making under pressure gave teams pause. Here's a glimpse at his scouting report:

"With near-elite arm strength when he's set, Glennon works best when he gets to his drops, progresses across the field, and is able to sling and get the ball across the field. His ball placement on stick or timing throws, including from different foot platforms, is ideal. His velocity, consistent clean ball and ideal mechanics allow him to get into a rhythm and exploit openings. ... Questions remain regarding his composure. He can get rattled, lose his rhythm and confidence, shifting his eye level and using poor footwork and mechanics."

In his first career regular-season game as the Buccaneers starter, it was evident that he's still very much the player he was in college -- for better or worse. Standing tall at 6-foot-5 in the pocket with apparent confidence (especially early in the game), the Bucs gave him plenty of short passes and easy reads. Still displaying high velocity on those in-breaking slants, delayed screens and drag routes, Glennon orchestrated an impressive first quarter drive that lead to the Bucs' only touchdown.

However, as the game progressed, the Bucs weren't able to make Glennon comfortable when working down field. On five passes of 15 yards or more, Glennon wasn't able to complete a single one (though Kevin Ogletree did drop one early in the game). Over-reliant on his checkdowns, Glennon continued to try and work shorter routes to move the chains, including throwing nine passes to players that came out of the backfield.

Mike Glennon was 5-of -15 for 33 yards under pressure, including an interception and two sacks, according to ProFootballFocus.com. While some of that was because he didn't audible at the line, Glennon's lack of escape-ability and limited core strength to brush off rushers will continue to be problematic, especially on A-gap blitzes, for much of his career.

The Bucs' offensive game plan was focused on giving Glennon confidence through completions early on in the game -- a standard idea to get a young quarterback going in his first NFL start. But Glennon's arm strength and ability to test teams vertically off play action weren't used enough. Those are tools that the Bucs will likely build on for the rest of his starts.

Despite Glennon's limited mobility, the Bucs have a talented offensive line that can give him time in the pocket and let his big-bodied receivers win one-on-one matchups.

Glennon flashed rookie tendencies in his first NFL start, which is to be expected. He didn't play well after the first quarter, but he did show a grasp of most of the basic throws in the Bucs' offense. If he can improve his decision making, feel more comfortable pre-snap against rushers, and get the opportunity to test teams in the middle of the field and vertically, Glennon could very well begin to thrive in this offense.

It'll take some time before starting Glennon pays dividends for the Bucs' offense. But for the foreseeable future, Schiano and Glennon will be tied to the success of this team.
