Following up with a few thoughts on free-agent tight end Dallas Clark visiting with the Patriots on Tuesday:
One of the first things that came to mind is that the team can never have enough information. Clark is a good player who has hurt them in the past. He's available. So in the event the Patriots want to make a move at tight end (right now they are well stocked), a visit like Tuesday's provides a clearer road map for them, possibly giving them a better feel for where Clark is medically (he's missed 15 games over the last two seasons).
In essence, this looks like a case of due diligence.
Another factor to consider is that when the Patriots signed veteran tight end Daniel Fells to a three-year deal on March 19, Clark was available at that time. The Patriots picked Fells over Clark.
The Patriots project to keep three tight ends on their final roster -- Rob Gronkowski, Aaron Hernandez and Fells. If one of them gets injured, then what?
Perhaps that's when Clark could come into play, assuming he's still available.
