Alabama would be higher with a healthy Tua. Mac Jones did play well against Auburn but his two pick-sixes were the difference, and those sorts of mistakes can't happen with Alabama's porous defense.
might feel a little low but they beat no one highly ranked, ala clemson, and sure injuries played some and scheduled teams are those teams but i am ranking on what they have done so whatever
Probably going to curb stomp their bowl opponent... or quietly slip away in an upset into the night. Either way, this team was really good but you can't be amazing every year, every game. Just 99% of them. 
What's Alabama's best win? You tell me. Very similar to Utah except that Utah won their division and Auburn is ahead of Bama due to H2H with the better wins making the extra loss comparable to Bama's weak schedule with one fewer loss.
Losses to LSU and Auburn. Best win is Texas A&M? Yikes. This is probably a better team but they didnt really earn being higher. Could move up after bowl. Right now their resume looks a lot like Utah's.
