Here's where Ryan is wrong. The coaches' booth for both teams includes a standard broadcast truck feed, which is pumped in via the instant replay booth. Even if it was not seen in the stadium, Ryan's team had access to a replay of the Maclin catch on the standard broadcast feed. Between the completion of Maclin's catch and the start of the next play, the Bills had roughly 34 seconds to decide whether or not to challenge the play (by my count). Even if there was a malfunction inside the booth with the broadcast feed, it was probably enough time to access a backup replay of the catch.
