I don't think any of the gents you mentioned are Tier 2. To me Tier 2 should be able to beat Tier 1. I don't see any of them beating Alirez or Mendez. Bartlett? Sure.
141 Tiers to me:
Tier 1 - Mendez(tOSU), Alirez(UNC)
Tier 2 - Bartlett(PSU)
Tier 3 - Hardy(UN), Happel(UNI)
Tier 4 - Lemley(UofM), Koderhandt(Navy), Schwartz(OU), Swiderski(ISU)
Tier 5 - Vombaur(Minny), Titus(WVU), Vasquez(ASU), Cornella(Corn), Edmond(Mizzou)
Tier 6 - Henson(LHU), Composito(Penn), Hines (Leh), Olivieri(Rut),
Need to see more - Cannon(NW), Hughes,(OSU), Orine(NCSt), Latona (VT)
All four of the 'see more' gents are coming up from 133. Not everyone can do that, and until we see that with them, they don't get 'Tiered' by me. This is kind of from the hip, and I am sorry if I missed someone.
I could see Swiderski being argued in to Tier 5 because he has losses to two guys in that tier, however I could see him beating Hardy and Happel. Tier 5 is a complete shitshow. They could lose or beat anyone from 4-6, so that is a fun go-round.
*Keep in mind the way my 'tiers' work is that you can beat an opponent one above you and lose to an opponent one below you, but you shouldn't expect to beat or lose to someone greater than one tier away from you unless injury or pinfellery or something out of the ordinary happens
Edit: Keep in mind we have a sample sizing of Swiderski at 141lbs as well. It wasn't nearly as good as last year at 149lbs. Was that due to weight management, youth, or a mixture of both?
