Oregon released an updated list of weights for its players on the morning of its first spring practice Tuesday, highlighted by a couple near-30-pound increases along with some smaller improvements from the Ducks' most important players.

Here is the complete list of notable changes, per Matt Prehm of Duck Territory on the 247Sports network:

Notable Oregon Weight Gain in 2014 Offseason Player Old Weight (lbs) New Weight (lbs) Change (lbs) DL Sam Kamp 258 287 +29 OG Doug Brenner 279 305 +26 QB Damion Hobbs 195 220 +25 DL T.J.

Sam Kamp tops the list and jumps off the page for obvious reasons, having added 29 pounds from a season ago. Recruited as a sprightlier 240-pound, 3-star defensive end, Kamp now looks poised to crack the rotation at defensive tackle.

Also standing out is rising sophomore tight end Johnny Mundt, who added 20 pounds to his frame after a breakout freshman year that saw him replace troubled starter Colt Lyerla (who left the team around the time of a cocaine arrest in October) and finish with 16 catches for 281 yards and three touchdowns.

Further but not far down the list lie some of Oregon's top projected contributors in 2014: Junior defensive lineman Arik Armstead gained 17 pounds, sophomore running back Thomas Tyner gained 14 pounds, senior cornerback Ifo Ekpre-Olomu gained 10 pounds and junior wide receiver Bralon Addison gained nine pounds.

The last two players listed above, Ekpre-Olomu and Addison, are arguably the most talented outside-the-numbers players on Oregon's defense and offense, respectively. Though their games are predicated more on speed and agility than power, putting on weight—provided it's the good kind—should help them build on 2013 and hold up better against physical teams (read: Stanford) this season.

Oregon will hold its spring game on Saturday, May 3 at 2:00 p.m. EDT
