Even though Jennings had that good punt return, morton has been much better at returning punts this of season. I would think ponder is the odd man out, he is one of the best in the league, but being in couglins doghouse and performing poorly this pre-season hurt his chances.
Also, since ward is out for a significant amout of time, morton could plug into the #3 spot.
I'd like to see jennings on a KR with his blazing speed, but morton is the no doubt starter at punt returning.
