ALLEN PARK — One of Matt Patricia’s many stamps on Lions practices comes in a pixelated display hanging next to the scoreboard in Allen Park. It’s a jumbotron that allows coaches to watch plays from another angle as they happen, and it’s something he’s hoping can elevate the way Detroit runs practices.

Its effect remains to be seen, but it did attract one Hall-of-Famer on Thursday. Mike Singletary was the day’s guest, there to check out the technology a much younger first-time head coach was implementing into his practices.

Singletary is now the coach of Alliance Memphis of the Alliance of American Football league that is launching this fall. He’s back into a form of pro coaching again, and that means he’s in the market for pointers, too.

The 10-time Pro Bowl linebacker with the Bears got to take in the third and final practice of the mandatory veteran minicamp at Allen Park. He didn’t know Patricia prior to reaching out about the video boards. On Thursday, he got to observe the new Lions coach’s up-beat demeanor, which includes more conditioning and a little more screaming than the Lions were used to under Jim Caldwell.
