Mcintyre is what he is... The guy is 27 and has gotten plenty of snaps where everyone should have a good feel of his skillset.
He has decent strength and a good motor. Laterally he's pretty ahtletic, and that's what set him up to make some good plays on Ben. He simply had the athleticism to deal with Ben trying to shrug him off.
Where he's bad is that he's not the fastest guy in space and he also doesn't have overwhelming strength to make up for it.
Thomas is still better against the run but McIntyre is probably better against the pass. McIntyre will probably get more chances to rush the passer instead of Maybin due to the fact that Maybin has been pretty useless so far.
