If Chip Kelly is re-evaluating the occasionally stagnant and often predictable coaching strategies that blemished the end of his stint in Philadelphia, he’s doing so internally and of his own volition.

“I don’t really care what people say or blog about,” Kelly said Friday. “We don’t sit in our meeting room and say, ‘Hey, somebody blogged about this. Let’s talk about this.’ So, we’re just trying to get first downs and score points against whoever we’re playing that week.”

Questions involving Kelly’s stubbornness to adapt his offense to a league chock-full of acclimating defenses were raised in an article published Friday on The Ringer by Chris B. Brown.

In his synopsis of Kelly’s struggles with the Eagles, Brown noted several instances in which opposing defenses called out the offense’s plays before the snap — particularly run plays based on the alignment of the tight end.

Brown also suggested, as others have, that Kelly needs to diversify his play-calling in order to be successful in the league. He went on to say that, in his evaluation of the 49ers preseason, Kelly looked to be approaching the game with a fatally similar strategy.

Kelly refuted the notion this morning when asked about his willingness to change his offense.

“We go into every offseason trying to improve in every aspect that we do,” he said. “Whether it’s player acquisition, player development, teaching in the classroom, strength and conditioning. I think in everything, you’ve never arrived at this game and you’re always striving to get better in every aspect of what you’re do. So, to think that we haven’t changed or won’t change just because of whatever, I don’t get that.”

Whether Kelly intends to change his offense is not the issue — what matters is if he can change it enough to keep the defense honest. If opposing teams are calling out your plays, then the offense is predictable, and the game plan needs more variance.

It’s possible that Kelly is covertly implementing nuances that will complement the system he’s established and waiting to unleash them when the games actually matter.

It’s also possible that his refusal to acknowledge what’s being written about him is either feigned or a display of disdain for such a simplistic evaluation of complex NFL schemes.

Still, for a man who’s arrival in San Francisco was practically predicated on learning from past mistakes, it’s tough to hear that he isn’t willing to consider criticisms, even from bloggers.

Especially since some of those bloggers, and Kelly’s former players, make a pretty compelling argument.
