I believe it's 4, if Tyson isn't a counter.
I don't think that will be an issue at all. I would expect at least 4 grad transfers after spring ball from the reporting I've seen. Here are the possible transfers that I've seen mentioned on other articles talking about depth a few days ago (
2020 Alabama Football Roster Update):
WR - Shavers or Townsend
TE - Parker, Latu and then Tennison if he gets passed up by Tucker
OL - Randolph or Owens if they get passed up by Ekiyor
DL - Wynn and/or Mathis
LB - Moody was talked about as a possible
Kickers - Bulovas and or Delong
I'm sure there are more and it's always a fluid situation with injuries and performance gains.... so I don't worry to much about it, but looking up and down the roster I would expect 4/5 transfers to be a given by end of spring/summer.
