IDK, many were down on Allen and questioned him from a couple of tweets too, but he & Jackson were more proven then Lance, I'm just comparing the accuracy angle because that was in question with both Allen & Jackson and let's not forget, many wanted Jackson to play WR, please don't act like Jackson was a sure thing at QB.
Kyle Shanahan has made every QB he's been around better, Cousins, Ryan, Garoppolo & even Nicky Mullens, so as much as I hope that Lance is a bust, I'm betting on Shanahan because of his history with QB's, but again, I hope Lance looses every game he plays against the Los Angeles Rams.
