There are plenty of examples of poor mechanics or arm strength, but you have to look at what type of offense they were recruited for. Martinez was not brought into a pass happy offense, they run spread, speed option and utilize their running attack to open up play action. They are not a team that is typically going to throw for 300 yards a game, but more interested in forcing opponents to roll up a safety and get man coverage.
UND needs a QB that has solid arm strength and accuracy and smart enough to run the offense, make the right reads, while managing the game. In my opinion, a good QB makes average WR's look great, so with the talent we have at receiver, bringing in a solid, smart, pro-style QB, regardless of mechanics is much more important than what his perceived throwing motion looks like to the average fan.
Unless you are or have been a college/professional QB coach, you probably don't have enough knowledge to be breaking down the mechanics of anyone, so please leave that to the ones who are paid to do so and quit shredding potential players that may decide not to come to UND, because of the negativity and will go somewhere they are appreciated.
