Dolphins add three more undrafted free agents

The Dolphins have added three more undrafted rookies, bringing the grand total to eight. Newly signed are Temple center Alex Derenthal, Stanford running back Anthony Kimble and Tulsa wide receiver Brennan Marion.

Alex Derenthal

A four-year starter for the Temples Owls, Derenthal started all 47 games possible during his collegiate career and earned second-team All-MAC honors as a senior in 2008.

As reported earlier on this site, Derenthal worked out for the Dolphins in late March. He was ranked the 719th prospect in the draft by NFL Draft Scout.

Update: Derenthal was not listed among Miami's signed undrafted rookies. Therefore, it is likely the reports of him signing were erroneous, and he is likely merely trying out at the team's upcoming minicamp.

Anthony Kimble

Kimble's numbers steadily improved in four seasons for the Stanford Cardinal, rushing for 244 yards and two scores as a freshman and capping things off with 717 yards and six touchdowns as a senior. He finished his collegiate career with 1,940 yards on 415 carries (a 4.7-yard average) and 18 touchdowns.

This offseason, Kimble just barely cracked Draft Countdown's list of running back prospects, ranking 27th out of 29 total backs.

Brennan Marion

A two-year starter at Tulsa after transferring from DeAnza Junior College in 2007, Marion was a tremendous deep-play threat for the Golden Hurricane, breaking the NCAA record for yards per reception as a junior at 31.9!

Topping 1,000 yards both years at Tulsa despite never catching more than 43 passes in a season, Marion finished his collegiate career with 82 receptions for 2,356 yards and 19 touchdowns.

Marion tore his ACL on the final offensive play of the Conference USA championship game in December 2008, which likely hurt his draft stock and could impact his availability in the Dolphins' offseason activities.

Interestingly, Draft Countdown had Marion as the 37th-best wide receiver prospect in this year's draft—one spot ahead of Dolphins fourth-round pick Brian Hartline.

Analysis

Of the three players discussed in this article, Marion is clearly the most talented and thus has the best chance of sticking around. He's only six months removed from the torn ACL suffered at Tulsa, so he's likely destined for the practice squad or stashed on injured reserve in 2009. Still, there's no denying his talent and he could end up being a steal for the Dolphins down the line.

Kimble's best chance at staying in Miami is on the practice squad, where he'll have to beat out 2008 sixth-rounder Lex Hilliard for a spot. Neither one of them has a realistic chance at jumping Patrick Cobbs for the No. 3 tailback job.

As it stands, Derenthal is the only other pure center on the roster behind starter Jake Grove. However, guards like Joe Berger and Andy Alleman can play center and have a lot more ability than Derenthal, so he has quite a few bodies in his way if he wants to make the team.

Derenthal is extremely borderline pro prospect and doesn't stand much chance of sticking around. He's got experience but is simply limited physically and probably doesn't have what it takes to make it in the NFL.
