There is not going to be a lot of UDFA signings for the Texans. Texans had 74 players on the roster before the draft. You can only keep 90 players max on the roster during training. With the three or 4 UDFA the Texans already have, there's only room for a couple more players.
Nick said 5 - 6; but not quibbling with you. I do expect us to sign several vet FAs on Monday afternoon Also CJ Dippre to NE
Aaron Wilson has reported about 4 UDFA to the Texans so far. I don't know if those 4 will still be there on Monday. The UDFA WR from Minnesota will probably change his mind once he finds out there are 12 WR's on the roster. I expect maybe one or two more UDFA by Monday. Nick likes having a lot of veterans in the mix. By comparison the Vikings have already signed 19 Undrafted free agents.
