Struggles to slip blocks at the second level and is easily cut down on contact; ends up on the ground far too much. Doesn't do a great job taking proper angles inside the box either in the run game. Will overrun plays and is slow to redirect and get after the football. Works hard in pursuit but isn't a real physical striker into contact. Attacks ball carriers too high and doesn't create much force at the point. More of a drag down guy who starts high, slips down toward the legs and is just really inconsistent in that area of the game.
Impression: He's limited athletically, will struggle in space at the next level and doesn't showcase much as a tackler when asked to break down vs. the NFL-caliber backs he faced. More of high character/effort free agent who will struggle to make a team."
He received one of five prestigious National Football Foundation National High School Scholar-Athlete awards before his redshirt season, and his first year on the field saw him rack up 37 tackles in reserve duty. He then earned honorable-mention Mountain West honors in 2008 (88 tackles, three interceptions, nine pass breakups), second-team all-conference accolades in 2009 (140 tackles, 3.5 TFL, six PBUs, two forced fumbles) and 2010 (108 tackles, two INTs, five PBUs, two FF).
Prosinski's excellent pro day workout (4.39 40, 39.5-inch vertical, 4.28 short shuttle, 6.85 three-cone), in addition to his durability, intelligence and production, will help regional scouts to sell their superiors on the tough safety's merits as a late-round addition to the roster.
Positives: Centerfielder with straight-line speed and high football intelligence. Excellent closing speed when getting to the sideline or to ballcarriers over the middle. Most secure tackler on the team when technique is sound, keeps legs moving and uses arms to wrap after contact. Also cuts down ballcarriers with his shoulder when coming downhill. Recognizes routes coming into his area and has the recovery speed to get the angle on running backs down the opposite sideline and deep throws from play-action. Breaks up passes in front of receivers, at times making the interception, without interfering. Team captain in 2010.
Negatives: Sometimes resorts to ducking his head on open-field tackles instead of staying low and square. Not an intimidating hitter. Hesitates when plays slow down instead of inserting himself into the pile to prevent further yardage. Engulfed near the line on run plays by linemen and larger tight ends. Inconsistent finding his way through trash when flying up into the box."
Positive: Aggressive, run-defending safety who is best playing downhill. Fast up the field, shows a closing burst, and keeps the action in front of him. Takes good angles to the action, plays with an aggressive style, and is a hard-hitting defensive back. Shows good awareness between the numbers.
Negative: Slow pedaling in reverse, bites on receivers' moves, and displays marginal ball skills. Late getting to the spot in coverage and struggles with the fundamentals of the position.
Analysis: Prosinski was a dominant run-defending safety the past two seasons, but limited size and speed gives him marginal upside for the next level. He comes with a special teams mentality, which will be his ticket onto an NFL roster."
2009: Prosinski was voted Second Team All-Mountain West Conference at the conclusion of the 2009 season in balloting by the nine MWC head coaches and media from around the conference.

2007: While Prosinski did not start any games in 2007 as a redshirt freshman, he played a significant role for the Cowboy defense as a backup safety. Prosinski was credited with 37 total tackles, 15 solos and 22 assists. He also broke up one pass. Despite not starting, he ranked 12th on the Cowboy squad in tackles. His best individual game came against BYU as he was credited with 13 total tackles. He also had a six-tackle performance at Utah.
2006: Redshirted. During the `06 season, Prosinski received a very exclusive honor as he was named one of only five former high school football student-athletes in the nation as a 2006 National Football Foundation (NFF) National High School Scholar-Athlete. Prosinski was the West Region honoree. Of all the high school football players in the nation approximately 2,500 are honored annually by the 120 NFF chapters across the country with NFF scholarships.

Prosinski was also recruited by Air Force, Boise State, Colorado State, Georgia Tech, Harvard, Montana State, Princeton and Utah State. He is majoring in business at Wyoming.
Strengths: A physical safety who is a smart, disciplined player. Plays well versus the run, as he takes good angles to the ball and delivers explosive hits on ball carriers. Smart in coverage who reads routes well and puts himself in position to make plays. Makes plays on the ball. A competitive player who plays to the whitsle and gives great effort every play.
Weaknesses: Lacks great speed and athleticism that leaves him vulnerable in coverage, especially man coverage. His balance in space suffers due to his average athleticism, as he will miss tackles occasionally in one-on-one situations.
Projection: Seventh round or UDFA depending on how he tests. Prosinski could make a practice squad or contribute on special teams as a backup."
