I think this is just a silly discussion. Of course Smyrna is legit. They are clearly one of the top 4 teams in the state by anyone's standards. They were legit for sure starting in game three when they went toe to toe with Sallies (one of the best, if not THE BEST, in the state then and now). After that they blew the doors off anyone team they faced, including ranked opponents.
As for Smyrna not playing anyone...thats just silly too? Smyrna plays who they have to play (which is generally the most competitive conference top to bottom) plus they went out and scheduled a decent Appo team, a decent D2 team in Howard and the states powerhouse team most years, Sallies. If you go team by team, Smyrna's schedule is very comparable to Wm Penn. Both played a good D2 school and both played and lost by more than 2 scores to the #1 team in the state. Both are 4-1 against the top 10 D1 ranked teams in the state. I do feel Wm Penn's schedule was slightly tougher because one of their conference games was Mtown, who is better than any of Smyrna's conference opponents.
Unfortunately some people don't want to give Smyrna credit because its their first go around at the big boy table and don't have the banners in the gym. If thats your criteria, then its true...Smyrna isn't the greatest team to play D1 football throughout history. But in 2015, Smyrna is legit...there is no question about that. We will see if they are the best of 2015 if they win the championship. There is only one best team...thats the champion. But there are several legit teams.
