‘Singletary is candid that adapting to Dorsey isn’t instantaneous, even if there is a helpful level of familiarity. The Bills used OTAs and minicamp to experiment with all parts of the offense, a process that will continue into training camp. While Singletary thinks it has been a smooth transition from Brian Daboll to Dorsey, he feels it’s too early to make any major declarations about how he will look in the Bills offense.’
