I love Brent. His voice is iconic and lends itself to that "big game feel." I'll really miss him and I especially hate that he's going to do SEC games. SEC already has the very capable CBS stable of broadcasters.
Maybe Fowler can reach Brent's status someday. I think Fowler is a pro. My dad never liked him though because in Snyder's early days he'd always take pot-shots at Snyder's scheduling, comments (my dad thought) could be attributed to his CU Buffs background.
