At OL, Hiestand is a significant improvement over Quinn from a development standpoint. Quinn was the better recruiter though. Still, calling this one an improvement.
At WR, almost anyone with a pulse would be an improvement over Del, but I really like all I've heard about Stuckey. Given the WR room was decimated in the last year, calling this an improvement.
At ST, Polian was pretty meh as a coach. Mason is regarded as one of the best ST coaches in college right now. Another improvement.
At DL, Washington is the better recruiter, Elston the better developer. Washington did GREAT things with the Boston College DL when there. At worst, we'll call this a push.
With LB, RB, and DC left, I'm not worried AT ALL that Freeman/Notre Dame won't hit on those hires with what I am seeing so far.
