Colts' Ryan Grigson, Joe Philbin in attendance at Michigan State pro day

Colts offensive line coach Joe Philbin was in attendance at Western Michigan's pro day on Tuesday to get a first-hand look at lineman Willie Beavers, and Philbin didn't have far to go afterward to continue his evaluation of offensive linemen..  Today, he is again at a pro day in Michigan, as he is on hand for Michigan State's pro day.  Joining him for this one is Colts general manager Ryan Grigson, according to NFL.com.

The most notable player at Michigan State's pro day is indeed an offensive lineman, as tackle Jack Conklin is expected to be a first round pick and has been projected to the Colts in a number of mock drafts.  The Colts met with Conklin at the NFL Combine, showing that they do have at least some degree of interest - or, at the very least, doing their due diligence on a player who might be available when they pick in the first round.  Conklin started 38 career games at Michigan State and was named a first-team All-American in 2015.  He spent most of his time (35 starts) at left tackle, though he did make three starts at right tackle as well.  Furthermore, some wonder whether he could play guard in the NFL, but that depends on what teams want to do with him.  The Colts have a left tackle already in place in Anthony Castonzo, meaning that if they do draft Conklin he would likely slide in at the right tackle position.

It's possible, however, that Conklin isn't the only player the Colts are paying attention to today.  Another Michigan State offensive lineman, though not as notable as Conklin when it comes to the NFL Draft, could catch Indy's eye too.  Center Jack Allen is ranked by CBS as the third-best center in this year's draft and is projected by them to be a third or fourth round pick, and he could be a very interesting option for the Colts at a position of need.  He was a first-team All-American in 2015 and, in 2014 was named a first-team All-American by the USA Today.  He is a two-time first-team All-Big Ten selection and a two-time Rimington Award finalist (awarded to the best center in the country).  A four-year starter, he played in 48 games and started 47 for Michigan State, finishing with the second-most starts by an offensive lineman in school history.  Most of his action (42 starts) came at center, though he did make five starts at left guard as well.  The center position is the biggest need the Colts have up front, so it wouldn't at all be a surprise to see them add one in the draft.  It's possible that, in addition to Jack Conklin, the Colts also have their eye on Jack Allen today as well.

UDPATE: In addition to Grigson and Philbin, Colts defensive line coach Gary Emanuel is in attendance at Michigan State's pro day as well and was putting some defensive linemen through drills.

Colts are well represented at Michigan State today. Grigson, and Joe Philbin (OL). Gary Emanuel (DL) putting guys through drills right now.
