As far as being negative about the 2-0-1 start is concerned, I think it’s valid as long as it’s not over the top.
The positive is that they are undefeated to state the obvious and the positive is that they are undefeated despite several units that are perceived to be strengths are vastly underachieving. Another positive is beating two teams that looked like probable losses to start the season.
However, they blew a 24-6 fourth quarter lead to Arizona, they were thoroughly outplayed in the second half by the Chargers and won largely because of a Chargers implosion and the Eagles had a decimated WR corp and still outplayed the Lions for long stretches so it’s a 2-0-1 record but it’s a shaky one.
All in all, some negativity is warranted after 3 games. You take the wins and be happy with the wins but you can also look at the big picture and see that winning isn’t sustainable over the long haul unless the Lions improve in some key areas, coaches included.
