That seems to be a bad habit that he picked up from Rodgers, who got it from Favre. Drives me nuts to see long balls just "thrown up into coverage" on 1st or 2nd down. Throw the ball out of bounds and live to see another down. I have less of a problem with those kind of throws on 3rd and long, when everyone else is covered. Might draw a PI and even if it is intercepted, if its a 40+ yard throw, probably ends up being similar to a punt.
Too often this year Jordan/Matt didn't seem to have a solid 3rd/4th down play call. Now maybe they did and Love just couldn't find a guy open. However, in my humble opinion, anything less than 10 yards needed for a first down should include Love rolling out, with the option to run and receivers being PAST the first down yardage, but no more than 1-10 yards past.
