It's a pretty weird conversation for sure IMO.
This season Love was:
#12 in "traditional" passer rating
#5 in QBR
#5 in ANY/A
#4 in NY/A
#10 in AY/A
#5 in Y/A
#4 in Y/C
#6 in TD percentage
#3 in sack percentage
And those are all very good, borderline ELITE numbers...
But, also...
#33 in completion percentage
#19 in yards
#11 in TDs
#13 in pass success rate
#16 in yards/game
Tied for 4th-most INT
And interestingly (to me) #31 in completions per game...and #30 in attempts per game. (Which is probably more of a coaching decision)
So it's actually really kind of hard for me to judge. The "bulk" stats (yards accumulated, total TDs and INTs) are honestly pretty middling. The advanced metrics are very, very good. I would think that with more passing volume it'd be reasonable to assume that the volume-based stats would go up, as well (i.e. if Love is generally a top-5 QB in yards per attempt and its various permutations, with more attempts you'd expect to see yardage go up exponentially).
With all that in mind then I guess my super quick surface-level/"gut" analysis of it would lead me to ask...why didn't we let Love loose a bit more?
