Look for a strong emphasis on throwing mechanics in QB recruiting going forward.
Although, Tommy and other recent QBs were pretty solid, no? What you could tell is a lack of focus on the fundamentals and coaching/drilling them once they got here. The previous staff had a "Just get the ball there, doesn't matter how" and "You are a running back who throws" philosophy, in more or less those same words.
Here's the thing. We still do not have a dedicated QBs coach on the staff. It's Langsdorf the OC, as it was Beck the OC. The difference? One guy intends to coach up his quarterbacks, and has the background for it.
