I don't think Carr would have it against Sta(l)rocci. At 174lbs he just doesn't match up well on any avenue. Sta(l)rocci is longer, stronger, bigger, better on top than Carr is on bottom, just as fast, and just as good neutral.
O'Toole got physically handled against Carr in their first two matches. Unless O'Toole spent an entire offseason growing in to 174lbs (which he did not) I would not give him a fart's chance in a shit storm against Sta(l)rocci this year.
I really want to see Trumble at Heavyweight next season. He is an entirely different wrestler when he wrestles 97 KG (213lbs) rather than 197lbs.
