My take on him is that he's had a very solid run of conssitently high performances in his first year starting, and as an experienced, learned, thinking QB that spent enough time watching how to do it and learning from the best. It's a good system, and it's showing fruit now.
It's always too early to judge a first year starter, even when they look this good right now, but all the signs are there, right now. I just think it's remarkable how this organization is able to do this with their first year starters (though I guess Favre was a mercy swap from Atlanta, right? But he started this current QB train, so maybe not the same origin story)
hopefully, though, and years from now, Love doesn't also turn out to be complete human garbage, like Favre and Rodgers, so that would be a nice break in the sequence
