2019 team starting to remind me of the 1988 squad: stout defense, winning low scoring games early, gunslinger QB, exciting rookie RB (although we haven't seen too much of DS), 4-1 after five, coach now coming into his own...the schedule is certainly favorable...maybe not a 12-4 team, but could be 11-5.
