Hoyer, who originally joined the Patriots back in 2009 as an undrafted free agent, rejoined the organization last November following the trade that sent Jimmy Garoppolo to San Francisco. Now 32, the well-traveled Hoyer brings NFL starting experience (including six last season with the 49ers) and familiarity with New England's passing scheme to the table, but he'll only see meaningful regular-season snaps in the event of an injury to starter Tom Brady. The Patriots did draft Danny Etling this April, but he's not expected to supplant Hoyer as the team's No. 2 quarterback. In the event that Hoyer is pressed into action, he can't be expected to replicate Brady's elite numbers, but with offensive coordinator Josh McDaniels calling the plays and a deep group of pass-catching weapons on hand, Hoyer would be capable of putting up decent fantasy production if called upon.

Hoyer took over for an injured Jay Cutler in Week 2 last season in Chicago and proceeded to throw for 300 yards in each of his next four starts, with six TDs and no picks. In his fifth start, he broke his arm, ending his season. Now with his sixth franchise, Hoyer reunites with head coach Kyle Shanahan, who as Browns OC in 2014 presided over Hoyer's only 3,000-yard campaign. Not that Hoyer was good -- he had a 12:13 TD:INT ratio in 14 games. Still, Hoyer has his best chance for fantasy relevance in Shanahan's pass-happy offense. Free-agent addition Pierre Garcon also reunites with Shanahan, and holdover Jeremy Kerley proved capable last year. In the backfield, fourth-round pick Joe Williams and free-agent vet Tim Hightower join oft-injured Carlos Hyde. The 49ers also figure to play from behind often, giving Hoyer more opportunities.

Hoyer will enter the season as the clear backup to Jay Cutler. After throwing an equal amount of touchdowns to interceptions over his first five years in the NFL, Hoyer broke out with the Texans last year, posting a 19:7 TD:INT along with a career-high 91.4 passer rating. Despite the impressive numbers, his limitations as a passer caused him to get benched for a short time in favor of Ryan Mallett. Based on his overall performance in 2015, he'll likely be able to run the offense successfully should Cutler be forced to miss time.

After two underwhelming years in Cleveland, Hoyer signed a two-year, $10.5 million contract in March with the Texans to compete with Ryan Mallett for the starting job. While Hoyer has the bigger contract, he also has the lower ceiling. Although he's gone 10-7 as a starter since entering the league in 2009, Hoyer has completed just 56.5 percent of his passes for 7.23 YPA and a 19:19 TD:INT ratio. With the Browns last season, he ranked ninth in YPA but finished 32nd among 33 qualified quarterbacks in completion percentage, struggling mightily down the stretch with a 2:9 TD:INT ratio in his final five games. The 29-year-old is a capable backup but doesn't stand out in terms of arm strength, accuracy, size or mobility. Mallett has better raw skills but much less experience, having made the first two starts of his career last year prior to suffering a season-ending torn pectoral. Whoever wins the job will have a nice collection of skill players to work with, highlighted by DeAndre Hopkins, Cecil Shorts, third-round pick Jaelen Strong and running back Arian Foster.

Hoyer will open the year as Cleveland's starter, but he's unlikely to hold off 22nd overall pick Johnny Manziel for more than a few weeks. Returning from an October ACL tear and throwing to a WR rotation that will be without Josh Gordon, Hoyer will likely struggle when he sees the field, at which point the stage will be set for Manziel. Hoyer was somewhat effective with Gordon on the field last year, though, throwing five touchdowns compared to three interceptions.

With the jury still out on Brandon Weeden, the signing of Hoyer by the Browns sparked a bit of conversation at the time of the announcement. He received his first career start last season, though his play in his two games of action failed to change the perception he's going to be anything more than a reserve. He completed 30-of-53 passes for 330 yards, one touchdown, and two interceptions. The support behind Weeden has grown since Hoyer arrived in Cleveland and he'll battle Jason Campbell for the backup duties this season.

Hoyer, who is ticketed for free agency after this season, has developed into a trusted backup for the Patriots, but if another team suffers an injury at QB, then the Patriots could consider dangling Hoyer, if they feel that Ryan Mallett is ready to assume the No. 2 QB job. That's something that the team is presumably still evaluating, however.

Though the Patriots drafted fellow QB Ryan Mallett this past April, he's viewed as more of a developmental project than an immediate threat to Hoyer's gig as Tom Brady's top backup. In any case, Hoyer remains next in line for snaps in the event of an injury to Brady.

As an undrafted free agent, the odds were stacked against Hoyer last year, but he'll head into the 2010 season as Tom Brady's top backup once again unless the Patriots make a move to add some veteran QB depth.

Like most undrafted QBs he's a bit of a project, but he enters a Patriots' system where he has a chance to be methodically coached up. If he sticks as a rookie though, he'd either have to beat out Matt Gutierrez or settle for a spot on the practice squad.
