No big innovations...but, to Tom's point, I have actually used purple "line chalk" to dip felt footballs in and laid out a grid in Excel, printed it on white cardboard and threw passes against it testing angle of QB/ball vs point of impact, distance, etc...My passing still sux, but, over thinking, over analyzing and over engineering is what I do...it all may prove to be helpful someday
I will say I do have a lot going on in my head around some electronic products and have doodled some circuits down, however, with working, tweaking, building teams and practicing and "normal" life stuff, I'm probably a long way off...
