Hoodie has always, to this day, taken players based on their strengths. He then implements those strengths in his weekly gameplan. Mac's success to this point isn't due to some rapid development, it's that he isn't asked to do more than what he already brought to the table. I find it a bit odd to say Shanahan doesn't know how to develop players. Yes, there have been a huge number of swings and misses at the top of the draft but players have developed. Do Kittle, Deebo, Warner, Bosa, Greenlaw, and Al-Shaair not count for anything?
