STRENGTHS - Marquardt flashes some solid athletic tools and possesses the prototype size for the position, with long arms and a frame that could get bigger without losing foot speed. He shows good knee bend and lower body agility in pass protection. He overwhelms the smaller players he plays against with sheer size during in-line blocking. He is capable of making an impact out in space at the second level. He looks quick off of the snap and gets into blocking position quickly. He comes out of his stance quickly with good foot quickness. He looks strong against the lesser competition he faces. He has a heavy punch and when he lands it he gains an immediate advantage because he keeps moving his feet. Marquardt can be effective trapping and pulling because he is relatively quick for such a big man, and he takes great angles into contact.
WEAKNESSES - Marquardt plays in the Division-II level of football, and until he is seen on the field against better competition there will be questions about his ability to hold up against the bigger, faster players in the NFL. He is too tall to play guard and will wither make a roster as a perimeter lineman, or he won't make it at all. He tends to play very tall, and as a 6'8" lineman, he will have to really work hard to play with leverage and with good pad level. He isn't going to wow anyone with his anchor because of his height, and he will struggle against power in the NFL. He must add bulk to both the lower body and the upper body and hands to have appropriate power in the NFL. There are times when he will stand around at the end of the play instead of finishing the play through the whistle. He missed the entire 2012 season with a broken foot.
SUMMARY - Luke Marquardt is a very intriguing player who will get drafted because of his size and overall upside because it won't be based on his play against inferior competition in the Division-II level. He is simply too big and has a relatively easy time against the lesser competition, and there will be a lot of projection when it comes to where a team drafts him. He is a massive tackle prospect who has some good athletic tools to work with, but he will have to show that he can keep that level of athleticism while adding bulk to play in the NFL. He is very tall and there will always be concerns over his ability to play with a strong base and with good leverage. He tends to stand straight up in pass protection and will struggle against bit power and speed in the NFL. He is a developmental prospect, but he does have good tools to work with. He displays good foot quickness and lower body agility in pass protection and is quick enough to help into the second level. He has enough foot speed to pull and make huge holes in college, and he does showcase a heavy punch when he lands it. He will need to improve the use of his hands and the accuracy of his punch for the next level. Overall, he is a solid developmental prospect that could be a nice value pick for a team because of his ability to move his feet as there aren't; many players who have his size and movement skills. He warrants consideration in the sixth-round by a team looking to add a player who could turn into much more down the road.
