He inherited a somewhat depleted roster from Pope (Pope brought Toolson, Averette, Harward, Lowell, etc with him to BYU)
First season was somewhat rough.
Second season = first WAC championship since 2014.
He has also landed a few nice recruits/transfers.
If Pope moves on from BYU in a few years - Madsen is setting himself up to be potentially the best available LDS HC on the market.
