2015 Packers offensive tackle preview: UDFAs battle for a job

Over the next few weeks, we will break down each position on the Green Bay Packers' 2015 roster in detail, discussing each player and making our predictions for the final 53-man roster.

Because the Packers managed to keep right tackle Bryan Bulaga and key reserve Don Barclay, there isn't a tremendous amount of opportunity for the incoming offensive tackles this year. Besides top starters and top backup, the team also has JC Tretter who can swing out from center if needed. For any other tackle to earn a spot on the 53 or practice squad, he must show more than just intriguing upside.

Here is our breakdown of the Packers' new additions at offensive tackle.

Fabbians Ebbele

Acquired: signed as an undrafted free agent
Age: 23
H/w: 6'8", 315 pounds
College: Arizona

Fabbians Ebbele stands out if for no other reason than his height. At 6'8", the former Arizona standout even towers over football mutant Julius Peppers.

Like most football players his size, Ebbele faces questions about his stiffness and ability to play with leverage. The last offensive lineman to make the Packers with comparable measurements was Breno Giacomini, but he didn't blossom until after departing Green Bay for Seattle. For the most part, the Packers prefer their blockers to be light on their feet, a mold Ebbele may not fit.

Vince Kowalski

Acquired: signed as an undrafted free agent
Age: 22
H/w: 6'4", 305 pounds
College: Villanova

In a literal sense, Vince Kowalski is player at the very back of the roster, having signed with Green Bay in June. That doesn't necessarily mean the team will limit his opportunities, however, as late signings like Chris Banjo have made the roster in recent years.

Still, for Kowalski to stick around, he likely needs to cross train at tackle and guard. Nearly every one of the Packers' backup offensive linemen play multiple positions. Kowalski started over 40 games at tackle during his college career, which should aid him during camp.
